Last month, Trump shook hands with Xi Jinping in Beijing. The two sides even announced a trade truce.
This week, the Pentagon went the other way. It added three of China's biggest firms to a military list.
The handshake and the blacklist are pulling apart.
The roster is called the "1260H list." It names firms the Pentagon ties to China's military.
The new update added Alibaba, Baidu, and carmaker BYD. It also named biotech firm WuXi AppTec and robot maker Unitree.
Being on the list brings no direct sanctions. So what's the bite?
Starting later this month, the Defense Department can't sign deals with these firms. By June 2027, it can't buy their products through middlemen either.
The Pentagon floated a similar list in February. Then it pulled the list while Trump's China trip was still on.
This update mostly matches that one. But it adds back two memory chipmakers.
The market barely blinked. Baidu's U.S. shares fell about 2%, while Alibaba and BYD each dipped less than 1%.
In short, traders shrugged. They have seen these lists before.

A list with no sanctions sounds toothless. But it isn't quite.
"These indirect restrictions could force some U.S. firms that work with the U.S. military to drop designated Chinese firms as suppliers," said Michael Hirson of 22V Research.
He called the move largely symbolic for now. Still, the label brands these firms as "military-civil fusion" players.
In plain terms, the Pentagon thinks their tech feeds China's defense base. Think of it like a no-fly list for government deals.
The firms can still sell everywhere else. But one big buyer now has to keep its distance.
Those national security worries are starting to shape money policy. They show up even with a fresh trade truce in place.
The named firms are fighting back. Alibaba said there's "no basis" for the tag and promised legal action.
Baidu echoed that, vowing to use "all options" to get removed. Carmaker NIO said the curbs won't hurt its business.
One listed name has an odd U.S. tie. Nvidia said last week it would work with robot maker Unitree on research robots.
This kind of fight has worked before. Xiaomi sued and won its way off the list back in 2021.
The timing is the real signal. It came just weeks after the Beijing handshake.
China called the move unfair and vowed to protect its firms. Even so, Hirson doesn't expect harsher steps from the U.S. Treasury this year.
After all, both sides still want to keep things calm. For now, the list is a warning shot, not a ban.
So the truce holds and the pressure builds at once. That's the U.S.-China story in 2026.
