WASHINGTON (Reuters) - Republican and Democratic U.S. senators introduced a bill on Tuesday that would reimpose sanctions on China's ZTE Corp 0763.HK000063.SZ if it does not fully comply with U.S. laws and an agreement with the Trump administration that ended stiff restrictions on the telecommunications equipment company.

President Donald Trump angered many members of Congress, including some of his fellow Republicans, in July when he decided to lift a ban on U.S. companies selling to ZTE, allowing the giant company to resume business.

Lawmakers have introduced several pieces of legislation since then that seek to clamp down on the company, China’s second largest telecommunications equipment maker. Most have failed to advance in the face of administration opposition.

Senate aides said they thought the latest measure - led by Republican Senator Marco Rubio and Democrat Chris Van Hollen and focused on adherence to an agreement reached by Trump’s Commerce Department - would get support from congressional leadership.

Senate aides said the purpose of the bill was to make it clear to the administration that Congress wants a strong response if ZTE violates the deal. Many members of Congress view the Chinese firm as a national security threat, worrying that the use of its technology in the United States could make it easier for China to steal secrets.

Among other things, the legislation, introduced by three Republicans and three Democrats, would require reports from the Commerce Department every 90 days on ZTE’s compliance with the agreement and sharing with congressional committees ZTE audits conducted under the agreement.

If ZTE is not in compliance, it would face stiff penalties, including paying $400 million now held in escrow.

“This bipartisan legislation would ensure that if ZTE once again violates trade restrictions or its agreement with the U.S., it will be held accountable in a significant, painful way,” said Senator Mark Warner, the top Democrat on the Senate Intelligence Committee and a co-sponsor of the bill.
