Philippines–Vietnam Upgrade: Manila and Hanoi elevated ties to an Enhanced Strategic Partnership as Vietnamese President To Lam visited, with new defense, digital transformation, tourism and education agreements signed and both sides stressing freedom of navigation in the South China Sea. Tourism & Flights: The upgrade includes a 2026–2029 tourism cooperation program aimed at boosting direct flight links and traveler numbers ahead of the 50th anniversary of diplomatic ties. Fuel Policy: Vietnam began nationwide E10 biofuel sales on June 1, requiring unleaded gasoline to be blended into E10 while E5 RON92 remains available until 2030. Trade Pressure: The US launched a Section 301 investigation into Vietnam’s intellectual property practices, raising the risk of future tariffs. Business & Investment: Vietnam’s manufacturing new orders rebounded in May to a three-month high, while private capital is shifting toward more disciplined, patient funding. Local Life & Safety: An E10 rollout is also driving a wave of related policy changes, and a Vietnamese court ruling clarified liability under Korea’s marriage brokerage law involving discriminatory materials. Regional Watch: Tourism across Southeast Asia faces strain from Iran-war-linked energy costs and uncertainty, with Vietnam and neighbors bracing for a tougher summer season.
