China and Vietnam expressed their support for maintaining a multilateral trade regime centered around the World Trade Organization in a joint statement issued on Tuesday at the end of a two-day visit by Chinese President Xi Jinping.

Xi Jinping is in Southeast Asia to build bonds with countries that also face U.S. tariffs and have come under pressure from Washington to curb the transshipment of Chinese goods.

During Trump's first term, tariffs on China were a big win for Vietnam, especially in cities like Haiphong. Now the country's future isn't so clear.
