The China committee of the US House of Representatives has asked Sequoia Capital to provide details about investments in artificial intelligence and other high-tech sectors in the country made by the venture capital firm and its former Chinese arm since 2010.

In a letter to Sequoia obtained by the Financial Times, Mike Gallagher and Raja Krishnamoorthi, the top Republican and Democrat on the congressional panel, respectively, asked Sequoia to list investments in groups developing AI, machine learning, chips and quantum that are based or have “significant operations” in China.

Sequoia has come under scrutiny from lawmakers amid security experts’ concerns about US capital flowing to groups in China that help the country’s military. It has also faced criticism over investments made by its former affiliate, Sequoia Capital China. The arm is in the process of splitting from Sequoia and is now called HongShan.
