South Korea Balances Protests, Trade Pressure and Rival Powers as Trump and Xi Meet

Seoul faces pressure from both sides

Roughly 28,500 American troops help underpin South Korea's security, while China remains its largest trading partner. Those two relationships are pulling President Lee Jae Myung in competing directions as his country hosts Donald Trump and Xi Jinping around the Asia Pacific Economic Cooperation summit in Gyeongju.

By October 30, 2025, the diplomatic gathering had brought a meeting between the American and Chinese presidents, efforts to secure relief from US tariffs, and a push for a joint statement called the Gyeongju Declaration. For Seoul, the challenge is to protect its factories, markets and security ties while keeping disagreements between the world's two largest economies from dominating the gathering.

Protests in central Seoul made the domestic pressures visible. Chants of "No Trump! No China!" accompanied demonstrations near the United States embassy and the gates of Gyeongbokgung palace. Police cordons separated the groups, whose signs targeted different concerns: Washington's renewed tariff brinkmanship and Beijing's growing influence.

Lee has sought to calm tensions at home while arranging separate meetings with both visiting leaders. His government backs legislation to curb hate rallies while maintaining the right to protest. The aim is to prevent public debate from becoming intimidation and keep attention on diplomacy.

The stakes reach beyond the summit venues. South Korean carmakers, chip producers, battery businesses and shipbuilders need access to markets and supplies connected to both powers. Their government is trying to make those relationships more predictable at a time when trade decisions increasingly serve security goals.

Why Gyeongju matters

Gyeongju is hosting APEC's first gathering on South Korean soil in 20 years. Xi's visit is his first to the country in 11 years, giving the summit added importance for relations between Seoul and Beijing.

Trump's presence brings a different set of immediate demands. The relationship with Washington now involves tariffs, controls on technology trade, and questions about the future of American forces on the peninsula. Lee's separate meetings with Trump and Xi offer opportunities to address those concerns directly without turning every discussion into a contest between the two visitors.

South Korean officials are seeking agreement on the Gyeongju Declaration. A joint statement would provide a shared position on growth and economic cooperation, something that proved impossible at APEC in 2018 when trade disputes blocked consensus.

The agenda includes making supply chains more reliable, preserving trade in advanced technology where possible, and reducing the risk of new tariffs on South Korean exports. Supply chains are the connected businesses and transport routes that move materials and parts into factories and finished goods to customers.

Several earlier developments explain why the host is approaching this gathering cautiously:

• In 2016, deployment of the US THAAD missile defense system was followed by Chinese economic retaliation, damaging South Korean views of Beijing.
• In 2018, trade disputes prevented agreement on an APEC joint statement.
• By October 30, 2025, South Korea was again trying to build consensus at APEC while managing pressure from both Washington and Beijing.

Seoul seeks tariff relief through investment

South Korean negotiators have been working against the clock with Washington as the United States makes greater use of tariffs and export controls. Tariffs are taxes on imported goods. Export controls restrict which products or technologies can be sold abroad and to whom.

The White House has sought new concessions from trading partners in return for relief. Seoul has floated an investment package for the United States worth hundreds of billions of dollars over several years, alongside discussions about expanded purchases of American energy.

South Korea hopes those commitments can protect its carmakers, electronics companies and shipbuilders from new penalties. Lee also faces friction over US immigration raids that swept up South Korean workers, adding a politically sensitive issue to an already crowded negotiating agenda.

Seoul's proposal combines continued cooperation with Washington on security and emerging technologies with an effort to keep business with China open and predictable. Officials describe their approach as damage control and risk reduction. The intended message is that South Korea can remain a reliable partner while protecting its economy from sudden disruption.

The investment package and energy purchases remain subjects of negotiation. No final terms or timetable for completing them are given, leaving companies dependent on the next stages of talks for clarity about their costs and market access.

Technology makes the old balancing formula harder

South Korean policymakers long described their strategy in simple terms: rely on China for the economy and the United States for security. Technology competition has made that division harder to maintain because the same products can matter to both commercial growth and national defense.

Samsung Electronics and SK Hynix illustrate the problem. Their memory chips help power smartphones and data centers around the world. China is both a major customer and an important production base for some South Korean companies, while the United States has tightened restrictions on advanced equipment used to make chips in China.

Decisions about factory machinery, investment and exports now require companies to consider security policies as well as customer demand. US pressure on advanced chips and equipment has reduced Seoul's room to maneuver, while sharper Chinese countermeasures have added another source of uncertainty.

Materials create a second vulnerability. South Korea imports critical minerals used in batteries and electronics, including rare earth elements that at times come almost entirely from Chinese suppliers. A disruption to those supplies can affect production even when factories have customers ready to buy their goods.

Seoul is widening its sources through deals with partners in Southeast Asia, Australia and the Americas. At the same time, it is maintaining contact with Chinese producers to avoid sudden shortages. That combination reflects the practical limits of changing suppliers while industries still need a steady flow of materials.

What Beijing and Washington want

Chinese Foreign Minister Wang Yi has presented the moment as an opportunity to improve ties with South Korea. During discussions with a visiting delegation from Seoul, he urged the two countries to expand their common interests, improve public sentiment and manage sensitive issues carefully.

Wang's message placed friendship and the handling of disputes at the center of the relationship:

Wang Yi said ties were at a critical juncture and called on both countries to uphold the direction of friendship, handle sensitive issues properly, and promote steady progress.

Washington's priorities put greater weight on deterrence against North Korea, meaning the military readiness and cooperation intended to discourage an attack. The United States wants closer coordination with Seoul, more active cooperation among South Korea, Japan and the US, and support for regional Indo Pacific arrangements aimed at countering coercive practices.

US officials have also pressed for trade concessions and floated changes to the American military presence and the sharing of its costs. Those discussions connect alliance management to economic negotiations, increasing the number of sensitive decisions facing Lee's government.

Seoul has kept disagreements with Washington behind closed doors, mindful that public clashes can make agreement harder. Its simultaneous engagement with Beijing seeks to preserve commercial ties while keeping the US alliance central to national security.

Trump and Xi hold their own talks

Trump and Xi met in South Korea on the sidelines of the APEC gathering, creating a summit within the summit. It was their first meeting in person since the US election returned Trump to the White House.

The discussion covered tariffs, access to markets and the restoration of channels for dialogue that had weakened in recent years. Officials on both sides described the exchange as constructive.

Trump, the US president, presented the talks positively afterward, stressing progress on commerce while leaving room for further negotiations:

President Trump said the meeting was a great success and that both sides had made progress on trade issues.

Xi's visit serves two related purposes. He is seeking a steadier relationship with Seoul and trying to prevent deeper economic separation, while also managing China's rivalry with Washington. APEC provides room for those individual meetings alongside wider discussions about growth.

For South Korea, improved dialogue between the two powers would help reduce the uncertainty facing its exporters and manufacturers. The host's immediate objective is to keep negotiations moving and secure a shared closing statement during a period when Asian economies need more predictable trading conditions.

North Korea adds another layer of risk

North Korea's closer ties with Russia over the past year have added a security concern to the economic discussions. Seoul and its partners fear that advanced military technology could reach Pyongyang, changing the risks faced by South Korea, Japan and American forces in the region.

China remains North Korea's traditional backer. Beijing is uncomfortable with aspects of a closer relationship between Moscow and Pyongyang that reduce its own role, while also seeing value in pressure on US allies. That leaves Seoul and Washington hoping China can quietly help restrain the North.

Trump has said he remains open to a future meeting with North Korean leader Kim Jong Un. South Korea says it is prepared for that possibility while concentrating on practical results at APEC.

Wi Sung lac, South Korea's national security director, described the country's role as a mediator seeking agreement on the summit's closing statement:

Wi Sung lac said many issues had been resolved and that the team was working toward a Gyeongju Declaration while acting as a bridge between the United States and China.

His description links Seoul's economic and security goals. Keeping Washington and Beijing engaged matters to trade, but both countries also influence the conditions in which South Korea must manage tensions on the peninsula.

What businesses need from a China reset

South Korean industry has interests at nearly every negotiating table. China buys a large share of its exports, including chemicals, screens and machinery. The United States is a premium market for cars, batteries and consumer electronics. Disruption to either relationship can put billions of dollars and jobs at home at risk.

Seoul is therefore pursuing tariff relief while exploring industrial cooperation with China in advanced batteries, sophisticated displays and clean energy supply chains. The aim is to preserve useful business relationships as restrictions on sensitive technologies become harder to navigate.

Officials on both sides have outlined practical steps for improving relations: regular meetings between senior leaders, working groups on supply chains and export controls, easier visas and more direct flights. More predictable contact could help governments and companies address problems before they interrupt trade or travel.

Dispute management is also part of the discussion. Fisheries in the Yellow Sea and telecommunications standards are among the areas where disagreements can spread into wider political friction. Regular channels would give both sides a way to address those issues before they dominate the relationship.

Limited engagement among South Korea, Japan and China is also back on the table after a long period of stalled cooperation. For Seoul, that provides another setting in which to keep conversations moving alongside its separate dealings with each neighboring power.

Public opinion limits Lee's choices

South Korean attitudes make diplomacy with both visitors politically demanding. Polls in recent years show lasting support for the US alliance and increasingly negative views of China across age groups. Many South Koreans continue to regard Washington as their indispensable security partner.

The 2016 THAAD dispute remains a central reason for distrust of Beijing. Chinese economic retaliation after the deployment left a lasting impression. Encounters over fishing in the Yellow Sea, along with recurring cultural and historical disputes, have added to public skepticism.

Younger South Koreans have been particularly skeptical of Beijing despite consuming news and culture across borders with ease. Lee must therefore show concrete benefits from closer engagement with China while weighing American requests against South Korean interests.

Negative attitudes toward China do not translate into a public desire for confrontation. They do make visible gains, respectful treatment and protection of national interests important to any attempt to improve relations.

The protests near the US embassy and Gyeongbokgung palace show that dissatisfaction can target either power. Lee's response has been to advocate pragmatic diplomacy and mutual respect while backing measures against rallies that become intimidating. His government wants to preserve the right to protest and present a calm setting for negotiations.
