Prime Minister Lawrence Wong's first official visit to China lasts until Thursday.

He met Xi on Tuesday morning at Beijing's opulent Great Hall of the People, with the Chinese leader urging their two countries to work to "stand on the right side of history and on the side of fairness and justice", according to state broadcaster CCTV.

He told Wong that "the world cannot return to hegemony or be dragged back to the law of the jungle", a veiled swipe at the United States, after President Donald Trump launched a barrage of tariffs this year on countries including China and Singapore.

Wong, in turn, told Xi he believed the Singapore-China relationship was "more important than before" in a time of "global turbulence and uncertainty".

"We can work together to establish closer ties and... continue to strengthen multilateralism and the rules-based global order for the benefit of all countries," Wong said.

Wong, who succeeded Lee Hsien Loong, the son of founding premier Lee Kuan Yew, in 2024, has warned the trade-dependent city-state could be hit hard by Trump's tariffs.

Although Trump imposed a baseline 10 percent tariff on Singapore, the country is vulnerable to a global economic slowdown caused by the much higher levies on dozens of other countries because of its heavy reliance on international trade.

Following his meetings in Beijing, Wong will head to the northern Chinese city of Tianjin for a meeting of the World Economic Forum.
