Nvidia stock gets Washington’s green light for H200 China sales — but Beijing adds a snag
Nvidia shares closed up 0.5% Tuesday after the U.S. eased export restrictions on H200 AI chips to China, but imposed new testing and security rules. China signaled it will approve H200 purchases only in “special circumstances,” creating uncertainty for demand. Nvidia denied requiring Chinese buyers to pay upfront. Other chip stocks saw mixed trading.
