Senate Minority Leader Chuck Schumer on Friday warned President Trump against a deal he reportedly reached with China to lift sanctions on one of its telecom firms, ZTE.

Trump told lawmakers ZTE would hire U.S. compliance officers and pay a large fine, after it was found to be doing business with Iran and North Korea, according to the New York Times.

Responding to those reports, Schumer, D-N.Y., said that’s not enough to abuses that have become an economic and national security threat to America.

“If the administration goes through with this reported deal, President Trump would be helping make China great again,” Schumer said in a statement Friday. “Simply a fine and changing board members would not protect America’s economic or national security, and would be a huge victory for President Xi [Jinping], and a dramatic retreat by President Trump. Both parties in Congress should come together to stop this deal in its tracks.”

Democrats have warned ZTE is a national security threat.
