Beijing has invited US memory chipmaker Micron to deepen its investment in China, six months after it banned its chips from critical information infrastructure in the country.

China’s commerce minister Wang Wentao invited Micron to “deepen its roots” in the country during a meeting with the company’s chief executive, Sanjay Mehrotra, according to a ministry statement on Friday.

Mehrotra “expressed his willingness to continue expanding investment in China”, the statement said.

The meeting comes six months after Beijing banned Micron’s products from critical information infrastructure after finding “serious network security risks”. The move was widely seen as retaliation against Washington’s restrictions on Chinese access to critical technology.
