WASHINGTON, April 1 (Reuters) - A U.S. Senate

investigative subcommittee on Tuesday is opening a review into

Facebook-parent Meta Platforms' ( META ) efforts to gain access

to the Chinese market and is seeking documents from the company.

Senator Ron Johnson, who chairs the Permanent Subcommittee

on Investigations, joined by Senator Richard Blumenthal, the top

Democrat, and Senator Josh Hawley, asked Meta CEO Mark

Zuckerberg about allegations it worked to build censorship tools

for the Chinese Communist Party as part of its efforts to gain

entry in the Chinese market, according to a letter seen but

Reuters.

The senators want Meta to disclose extensive records

including all Meta communications or records of meetings with

Chinese government officials since 2014 by April 21.
