China's President Xi Jinping called for support for the international system centred around the United Nations, trade and the rule of law as he continued on a Southeast Asian tour amid a sharp deterioration in China-U.

China's leader Xi Jinping started a week of diplomacy in Southeast Asia with a visit to Vietnam on Monday, signaling China' s commitment to global trade, just after U.S. President Donald Trump upended the global economy with his latest tariffs moves.

Xi Jinping has appealed to Vietnam to join China in upholding multilateral trade, as he begins a high-stakes diplomatic tour of the region’s major export-reliant economies in a bid to position his country as a stable partner in contrast to the United States.
