Despite a temporary easing in tariffs after their latest summit, Washington and Beijing’s broader contest over semiconductors, AI, and rare earths signals a long-term, strategic confrontation that continues to influence global supply chains.
Washington and Beijing have pulled back from an immediate escalation in their trade confrontation, but the wider rivalry over semiconductors, artificial intelligence and critical minerals is moving into a longer and more structural phase. According to reports from Washington and Chinese and US officials, Donald Trump and Xi Jinping used their latest summit to ease some pressure on tariffs and revive trade and investment talks, yet the result stops well short of a broad settlement.
The immediate benefit is a reduction in some of the uncertainty that has weighed on global commerce. Reuters has previously reported that tariff rounds between the two economies disrupted supply chains far beyond the US and China, and the BBC and The New York Times later noted that even when both sides agreed to partial truces, the deeper dispute over technology and industrial policy remained unresolved. That pattern appears to be continuing: the latest contact may cool the temperature, but it does not eliminate the underlying strategic contest.
For South Korea, that distinction matters. Large domestic groups such as Samsung Electronics and SK Hynix maintain production in China, which leaves them exposed to US export controls and licensing rules. Reuters reported last year that Washington ended the VEU treatment that had allowed certain semiconductor equipment to enter Chinese facilities more easily, shifting firms to an annual authorisation regime. That means the compliance burden for companies with plants in China remains substantial even if tariff tensions ease.
Critical minerals are another unresolved fault line. Reuters, the Financial Times and the Wall Street Journal have all highlighted the strategic role of rare earths in electronics, vehicle manufacturing and advanced defence systems, and the Chinese advantage in mining, separation, refining and magnet production gives Beijing significant leverage. As a result, any delay or restriction in Chinese exports could reverberate through South Korean industries that rely on those inputs, from cars and robotics to electronics and defence manufacturing. The immediate tariff pause therefore does little to remove the broader competition over supply chains, industrial capacity and technological leadership.
