Yahoo is shutting down what’s left of its operations in mainland China. The company just informed employees at a Beijing research center that it’s letting them go.

Yahoo is expected to terminate between 200 and 300 employees there, a Wall Street Journal report states today, citing a person familiar with the matter.

The Beijing facility employed mostly engineers and performed research and development projects for Yahoo. It’s the company’s only remaining office in mainland China.

“We will be consolidating certain functions into fewer offices, including to our headquarters in Sunnyvale, Calif.,” Yahoo said.

Yahoo has been in belt-tightening mode under the leadership of Marissa Mayer. The company has terminated between 700 and 900 people since last October, mostly overseas.
