Stateside companies that are suppliers for Huawei Technologies Co. or buyers of products and services from the Chinese telecom giant should be preparing for the possibility of the U.S. government meddling with that business relationship, according to trade lawyers.

The Trump administration has yet to sanction Huawei or issue an executive order barring the company from doing business in the United States. But the government’s ban last year against Chinese telecom ZTE Corp. showed that sweeping enforcement action “can happen overnight,” said Alexis Early, a senior associate in King & Spalding’s international trade group in Washington, D.C.
