President Donald Trump said he had reached a trade deal with Vietnam following weeks of intense diplomacy between the nations and ahead of a deadline next week that would have seen higher tariffs imposed on the country’s imports.

The US trade agreement with Vietnam reportedly lowers tariffs but lacks detail, triggering sharp warnings from Chinese officials.

The tariff deal between the United States and Vietnam sets the stage for a further climb in trade volumes between the countries and will also impact the energy generation mix that powers the fast-growing Vietnamese economy.
