The Trump administration and the Japanese government are in discussions to ensure that the bankruptcy of Toshiba Corp.'s U.S. unit, Westinghouse Electric Co., does not lead to U.S. technology secrets and infrastructure falling into Chinese hands, a U.S. official said on Thursday.

Westinghouse filed for bankruptcy last month, hit by billions of dollars of cost overruns at four nuclear reactors under construction in the U.S. Southeast.

The bankruptcy is likely to lead to the eventual sale of Westinghouse's nuclear business and Chinese interests have been seen as possible buyers, given the chance.
