US presidential trips abroad have traditionally been an opportunity to display the power of the American nation on the world stage. Donald Trump's five-day swing through eastern Asia, on the other hand, has been a display of the power of Trump - but also, at times, of that power's limitations.

Trump's stops in Malaysia, Japan and South Korea over the course of the first four days were an exercise in pleasing a sometimes mercurial American president. It was an acknowledgement that Trump, with the flick of a pen, could impose tariffs and other measures that have the potential to devastate the economies of export-dependent nations.

His sit-down with Chinese leader Xi Jinping on Thursday, however, was something entirely different. It was a meeting of equals on the global stage, where the stakes for both nations – for their economies, for their international prestige, for the welfare of their people - were enormous.

With China, Trump may flick his pen, but such actions come with consequences. They come with a cost.

For the first four days, Trump's most recent foray into global diplomacy was smooth sailing. Each stop was punctuated by a blend of traditional trade negotiations – deals made under the shadow of Trump's 'reciprocal' tariffs – and personal accommodations that at times bordered on the obsequious. In Malaysia, Trump secured access to critical minerals and made progress toward finalising trade arrangements with south-east Asian nations. He also presided over a treaty that should ease border tensions between Thailand and Cambodia – the kind of 'peace deal' the American president loves to tout.

In Japan, Trump's Marine One flew past a Tokyo Tower lit red, white and blue – with a top in Trumpian gold. Newly elected Prime Minister Sanai Takaichi detailed $550bn in Japanese investments in the US and offered the American president a gift of 250 cherry trees for America's 250th birthday, and a golf club and bag that belonged to Shinzo Abe, the assassinated former prime minister who bonded with Trump in his first term.

But as the Asia trip neared its conclusion, it became clear that the dynamics between Trump and Xi were markedly different. The lack of fanfare during their meeting highlighted the tension inherent in their relationship, shaped by tariffs, trade woes, and China's growing global influence. Both leaders agreed to ease some tensions during their meeting, albeit within a frame of mutual acknowledgment of the underlying frictions that continue to exist.

As Trump ultimately returns to America, the overarching question remains whether the agreements reached during his tour will translate into the sustainable benefits the US requires in its leadership role on the world stage.
