A senior US official condemned China's ban on goods from US chipmaker Micron Technology.
White House National Security Council spokesperson John Kirby said Beijing's position that Micron products pose a security risk was baseless.
China on Sunday ordered domestic operators of critical information infrastructure to stop buying from the US maker of memory chips. The government said the halt was necessary because it found serious network security risks in Micron products.
Kirby said on Wednesday that China's move was a reaction to a joint statement by the Group of Seven leaders in Hiroshima.
The G7 leaders called for coordinated efforts to counter economic coercion. The declaration was interpreted as referring to actions by China.
But Kirby said the Micron dispute hasn't sidelined efforts by President Joe Biden to reopen lines of communications with China.
Kirby indicated that the US is continuing to arrange a visit to China by Secretary of State Antony Blinken.
