Chip export controls emerge as US-China summit flashpoint


Wednesday, May 13, 2026

U.S. President Donald Trump and Chinese President Xi Jinping are scheduled to hold a summit in Beijing on May 14–15. It will mark Trump’s first visit to China in nearly 9 years, since 2017, and is already being viewed as one of the most consequential geopolitical events of the year.

The significance of this summit extends far beyond a routine diplomatic engagement. The world is simultaneously facing overlapping structural conflicts: U.S.-China competition over technology and supply chains, the Iran war and risks surrounding the Strait of Hormuz, and the reshaping of security architecture around Taiwan and Northeast Asia. The Beijing summit represents a critical inflection point where these strategic currents intersect within a single negotiating framework.

Most importantly, both Washington and Beijing have entered a phase in which neither side can fully exclude the other from the global system. The United States continues to dominate the dollar-based financial system, AI semiconductors, and cloud infrastructure. China, meanwhile, controls roughly 90% of global rare-earth refining capacity, more than 80% of the solar supply chain, and significant portions of the battery materials and manufacturing infrastructure. The two powers are competing aggressively while remaining structurally interdependent.

This Is No Longer a Tariff Negotiation—It Is a Negotiation Over Supply Chain Order

On the surface, the summit appears centered on extending the trade truce and managing tariffs. In reality, the core issue is supply chain control. Washington is maintaining restrictions on advanced AI chips and semiconductor equipment exports in an effort to slow China’s technological advancement. Beijing is responding by weaponizing rare earths and battery material supply chains as strategic assets.

U.S. export controls on China now extend to NVIDIA’s high-performance AI GPUs, advanced EUV lithography equipment, and high-bandwidth memory (HBM). China, in turn, is accelerating efforts to strengthen export management of critical minerals while rapidly building its domestic AI semiconductor ecosystem. In global markets, “de-risking” has increasingly replaced “decoupling” as the more realistic strategic framework.

This shift has direct implications for South Korea’s economy. As of 2025, China accounted for roughly 19% of South Korea’s exports, while the United States represented approximately 18%, effectively making both countries indispensable markets simultaneously. In semiconductors, both Samsung Electronics and SK hynix still maintain substantial production and sales exposure in China. As U.S.-China rivalry becomes more prolonged and institutionalized, Korean companies face growing pressure to recalibrate both supply chain and investment strategies.

Taiwan Is No Longer Just a Security Issue—It Has Become a Core Variable in the AI Economy

The most sensitive issue at the summit will be Taiwan. China is pressing the United States to draw a clearer line on the Taiwan issue—in other words, to state more explicitly that Washington does not support Taiwanese independence. At the same time, debates inside the United States are intensifying over the military costs and strategic burdens associated with defending Taiwan.

The deeper issue is that Taiwan is no longer merely a geopolitical flashpoint. Because TSMC produces more than 90% of the world’s most advanced semiconductors, stability in the Taiwan Strait is now directly tied to the stability of the global AI industry itself.

The race to build AI data centers has effectively become a race to secure HBM memory and advanced GPUs. AI investment by major U.S. technology firms is projected to exceed $300 billion annually by 2026, and the battle over AI infrastructure has already evolved into a strategic national industry competition. This is why tensions around the Taiwan Strait now reverberate across financial markets and global supply chains simultaneously.

As a result, the true objective of the summit is not to resolve the Taiwan issue, but to determine how far both sides are willing to establish guardrails against confrontation. What markets expect is not reconciliation, but manageable tension.

The Iran War and the Strait of Hormuz Are Also Central to the Summit

Another major backdrop to the summit is the Iran war. The meeting was originally expected in March but was delayed until May amid escalating risks around the Strait of Hormuz following U.S. and Israeli military involvement. China, heavily dependent on imported energy, has also become increasingly concerned about energy supply stability.

Roughly 20% of global seaborne oil shipments pass through the Strait of Hormuz. Any prolonged disruption could destabilize both global inflation and energy prices simultaneously. Washington hopes Beijing will use its leverage over Iran to help contain regional tensions, while China also has strong incentives to prevent prolonged instability in the Middle East.

This reflects a fundamentally different structure from earlier phases of U.S.-China rivalry. The two powers are competing intensely, yet both also require a minimum level of cooperation to prevent systemic disruption to the global economy.

North Korea and South Korea’s Strategic Space Are Also Under Pressure

For South Korea, the North Korean factor remains highly significant. North Korea has recently codified Kim Jong-un’s authority over nuclear weapons use in its constitution, further institutionalizing its nuclear weapons state framework. At the same time, the United States is simultaneously managing conflicts involving Ukraine, the Middle East, and Taiwan.

Under such conditions, if U.S.-China relations shift toward a managed stability framework, there is a growing possibility that the North Korean issue could once again be handled through a “status quo management” approach. China does not want instability in the North Korean regime, while the United States also seeks to avoid a new military crisis in Northeast Asia.

The challenge for Seoul is that its strategic room for maneuver could narrow considerably. South Korea remains overwhelmingly dependent on the United States for security, while remaining deeply integrated with China economically. As U.S.-China rivalry becomes more structured and prolonged, both sides are increasingly likely to demand clearer strategic alignment from Seoul.

Global Markets Are Expecting ‘Prevention of Breakdown,’ Not a Grand Bargain

Expectations surrounding the summit are, in many ways, surprisingly modest. Markets and diplomatic circles are not expecting a historic breakthrough. Instead, the primary hope is that bilateral relations do not deteriorate beyond a controllable threshold.

Indeed, many international strategic institutions interpret the summit less as a “normalization of relations” and more as an attempt to restore a degree of stability.

Yet the larger transformation lies elsewhere. The summit reflects a broader transition in Asia—from a U.S.-centered unipolar framework toward a more fragmented and competitive multipolar order. The United States is attempting to preserve order through military alliances and technological standards, while China is expanding its influence through supply chains and economic blocs.

At the same time, South Korea, Japan, India, ASEAN countries, and Middle Eastern states are increasingly moving to build independent strategic axes centered on semiconductors, energy, supply chains, and security cooperation. The trend toward strategic diversification across the region is becoming increasingly visible.

The Beijing summit is not merely another diplomatic headline. It is a defining signal of how Asia’s supply chains, security order, AI industry, and financial flows may be reorganized over the next decade.
