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 acknowledgment 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.

The main event of Trump's Asia trip came in its final hours, as he met with Xi. There, the power dynamic between leaders of the world's two largest economies was decidedly different than the interactions Trump had with his foreign counterparts in previous days.

During his previous meetings, Trump enjoyed a royal reception, but with Xi, the air was palpable with economic tension as both leaders discussed tariffs and trade.

As the world watches, the president's actions and decisions not only impact U.S. relations but also shape the strategic landscape across Asia - where allies reassess their partnerships amidst changing dynamics.
