AsianFin -- The Trump administration is pressing ahead with trade negotiations even after a U.S. appeals court ruled that most of President Donald Trump’s tariffs are unlawful, U.S. Trade Representative Jamieson Greer said Sunday.

“Our trading partners continue to work very closely with us on negotiations,” Greer said in an interview on Fox News’ Fox & Friends. “People are moving forward with their deals, regardless of what this court may say in the interim.”

Greer declined to specify which countries remain in active talks but noted he had spoken with a foreign trade minister as recently as Saturday.

The Federal Circuit Court of Appeals in Washington ruled 7-4 on Friday that while Congress granted presidents broad authority to respond to national emergencies, that power does not extend to imposing tariffs or duties. The decision threatens one of Trump’s central foreign-policy tools in his second term, which has relied heavily on tariffs to exert leverage in negotiations, despite the market volatility they triggered.
