President Donald Trump said he is “looking at” Chinese companies that trade on ⁦the NYSE and Nasdaq exchanges but do not follow U.S. accounting rules, according to Fox Business host Maria Bartiromo.

Bartiromo tweeted out a report on her interview with Trump that is airing Thursday morning. She didn’t elaborate on what he meant by “looking at.”

Trump did allude to the fact that the board overseeing the Thrift Savings Plan, a retirement-savings plan for federal workers, is deferring a change in the benchmark index it uses for its international fund to a gauge that includes Chinese stocks.

The Federal Retirement Thrift Investment Board was under pressure from the Trump administration and some lawmakers in Congress to delay the move. The savings plan was scheduled to transfer roughly $50 billion of its international fund to mirror an MSCI All Country World Index, which captures emerging markets including China.
