Microsoft has asked at least 100 of its employees in China to consider moving to other countries, according to Chinese state media reports.

The reports come as relations between Beijing and Washington deteriorate over technologies like artificial intelligence (AI) and clean energy.

Microsoft employees, mostly involved with cloud computing, were recently offered the opportunity to work in the United States, Australia or Ireland, among other countries, state-run outlet The Paper said in a report Wednesday, citing an unnamed source.

The Wall Street Journal reported Thursday that Microsoft asked as many as 800 employees — mostly engineers with Chinese nationality working on cloud computing and AI — to consider relocating. The Journal, which cited unnamed sources, reported last year that the Biden administration was preparing to restrict Chinese firms’ access to US cloud services.

CNN has reached out to Microsoft for comment.

In a statement reported by Reuters, Microsoft (MSFT) said providing internal opportunities for some employees was part of its regular business and the company remained committed to China.

The company entered China in 1992 and for decades has counted on its influential Beijing-based research lab — Microsoft Research Lab Asia — to help it build influence.

“Everyone is confused,” an employee told the Paper, as the affected staff has been given less than a month to decide.

Yicai, a Chinese state-owned financial media outlet, wrote that more than 100 employees were affected. It added that people had the option not to move.

The reports come in the same week President Joe Biden announced tariffs on $18 billion worth of imports of Chinese electric vehicles and an array of other products. Biden said he was trying to prevent unfair competition from China decimating US industries.

The tech war between the two economic superpowers has been intensifying for years. In October, the Biden administration limited the types of semiconductors that American companies can sell to China.

In recent months, the United States has also enlisted its allies in Europe and Asia in restricting sales of advanced chipmaking equipment to China.

Beijing has hit back by imposing its own curbs on exports of germanium and gallium, two elements essential for making semiconductors.
