UPDATE 1-U.S., Mexico, Canada to hold 'robust' talks on trade deal - statement

(Adds White House economic adviser on trade)

May 14 (Reuters) - The United States, Mexico and Canada will next week hold their first formal talks on their continental trade deal, with particular focus on labor and environmental obligations, the U.S. government said on Friday.

Trade ministers from the three nations are set to meet virtually on Monday and Tuesday to discuss the U.S.-Mexico-Canada (USMCA) deal, which took effect in July 2020.

"The ministers will receive updates about work already underway to advance cooperation ... and will hold robust discussions about USMCA's landmark labor and environmental obligations," the office of U.S. Trade Representative Katherine Tai said in a statement.

The United States is also reviewing tariffs which may be leading to inflation in the country, economic adviser Cecilia Rouse told reporters at the White House on Friday, a move that could affect hundreds of billions of dollars in trade.

The United States, testing provisions in the new deal aimed at strengthening Mexican unions, this week asked Mexico to investigate alleged abuses at a General Motors Co factory. (Reporting by David Ljunggren; Editing by Hugh Lawson and Jonathan Oatis)
