Two weeks ago, Xi Jinping warned Trump face to face that mishandling Taiwan could push the U.S. and China into open conflict.
This week, with that warning still fresh, the U.S. eased tariffs on Taiwanese goods to lock in a trade deal with the island.
The move signals Washington is willing to deepen ties with Taipei despite Beijing's warning.
The Trump administration is dropping aluminum, steel, and copper duties on aircraft parts coming from Taiwan, while capping the rate on auto parts, timber, lumber, and wood goods at 15%.
These were Section 232 tariffs, which the U.S. uses when it decides certain imports threaten national security. The metals duties have been in place since Trump's first term, making Taiwanese aircraft parts more expensive than rivals from countries without the same charges.
The cuts make official a deal Washington and Taipei agreed to earlier this year. As part of that deal, Taiwan promised to pump more money into the U.S. semiconductor supply chain and open its market to U.S. industrial and farm exports.
In return, Taiwanese exporters get cheaper access to one of their biggest customers, and Washington locks in a partner that controls the world's most important chip supply.

Tariff cuts usually happen quietly. This one isn't.
Trump met with Xi earlier this month, and Xi's message was direct: handle Taiwan carefully or risk pushing relations off a cliff. Beijing still claims the island as its own territory and treats any U.S. move toward Taipei as a threat.
Then this week, the U.S. handed Taiwan a tariff break anyway.
On top of the tariff move, Trump is weighing a $14 billion weapons package for Taiwan and has floated the idea of calling Taiwanese President Lai Ching-te directly - the kind of move that historically sets off alarm bells in Beijing.
A direct presidential call between Washington and Taipei would be one of the most public signals of U.S. support for the island in years.
Taiwan is home to TSMC, the company that makes the most advanced chips in the world. Apple, Nvidia, AMD - every U.S. tech name that matters runs on those chips.
TSMC has poured billions into new U.S. chip plants, but the most advanced production still lives on the island. Any disruption there - from natural disaster to military pressure - would hit the global tech economy fast.
So the tariff cut isn't really about aluminum or lumber. It's about locking in a friendlier trade relationship with the country that builds the brains of nearly every modern device.
Watch the arms sale next. If it gets approved, the careful balance Trump and Xi struck this month gets tested fast.
