Trump-Xi Summit April 2026: Trade War Reset or False Hope?

The US-China trade war entered 2025 at a fever pitch. Reciprocal tariffs climbed into triple digits — at one point reaching 145% on certain Chinese goods — threatening to sever supply chains that had taken decades to build. Paradoxically, both US imports and Chinese exports hit all-time highs in 2025, as businesses front-loaded orders to beat tariff deadlines. The turning point came in February 2026 when the Supreme Court ruled 6–3 in Learning Resources, Inc. v. Trump that the president lacked authority under IEEPA to impose country-specific tariffs. The ruling did not eliminate all tariffs — a blanket 10% rate on all trading partners survived under separate statutory authority — but it dismantled the architecture of escalating, punitive rates that had defined the trade war. For China, the SCOTUS ruling was a strategic windfall. The threat of 145% tariffs had been Beijing's primary leverage concern; with that ceiling gone, China's negotiating position strengthened considerably. For the Trump administration, it meant the upcoming Beijing summit needed to produce results through diplomacy rather than coercion.

On March 15, 2026, US Treasury Secretary Scott Bessent sat down with Chinese Vice Premier He Lifeng in Paris for what both sides described as 'frank and constructive' discussions. The meeting — held on neutral European ground — served as the critical pre-summit calibration session. According to reporting from Fortune and Al Jazeera, the agenda covered four pillars: China's dominance in rare earth mineral processing (where it controls roughly 70% of global refining capacity), potential Chinese purchases of US soybeans and Boeing aircraft as goodwill gestures, the scope of US high-tech export controls (particularly on advanced semiconductors and AI chips), and a framework for managing ongoing Section 301 investigations. Bessent reportedly came away cautiously optimistic, telling reporters the talks had 'cleared the underbrush' for the presidential summit. Chinese state media struck a more measured tone, noting the meeting was 'a step in the right direction but far from sufficient.'

With IEEPA tariff authority curtailed by the Supreme Court, the Trump administration pivoted to Section 301 of the Trade Act of 1974 — a statute that allows the US Trade Representative to investigate and impose tariffs on countries engaged in 'unfair trade practices.' On March 11, 2026, the administration announced investigations into 16 countries simultaneously, the broadest use of Section 301 in decades. The probe targets not just China but also the EU, Vietnam, India, South Korea, Japan, and others. For Vietnam specifically, the investigation focuses on alleged transshipment of Chinese goods through Vietnamese ports to avoid US tariffs — a practice that surged during the 2025 tariff escalation. India faces scrutiny over its digital services tax and restrictions on US agricultural imports. Section 301 investigations typically take 6–12 months to conclude, meaning any resulting tariffs would come well after the Beijing summit. But the threat itself is the leverage: it signals to all 16 countries that the trade war is not over, merely entering a new phase with different legal tools.

The Trump-Xi summit does not happen in a vacuum. Its outcome will reverberate across Southeast Asia, where countries like Vietnam have become both beneficiaries and collateral damage of the trade war. Vietnam's position is particularly delicate. On one hand, the country has been a major winner of supply chain diversification — FDI surged as manufacturers sought alternatives to China. On the other hand, the Section 301 investigation specifically targets alleged transshipment through Vietnam, threatening the very trade flows that fueled its export boom. Vietnamese officials have been walking a diplomatic tightrope: publicly welcoming US investment while privately negotiating with Beijing on supply chain coordination. For ASEAN broadly, the shift from 145% to 10% tariffs reduces the urgency of 'China+1' strategies. If US tariffs on Chinese goods remain at just 10%, the cost advantage of rerouting production through Vietnam or Thailand diminishes. This is paradoxically bad news for countries that invested heavily in attracting China-diverted manufacturing. The rare earth dimension adds another layer. China's dominance in rare earth processing means any disruption in US-China relations directly threatens the EV and semiconductor supply chains that ASEAN countries are trying to join.
