May 30 (Reuters) - The United States on Thursday said

worker rights' issues it had identified at Industrias Penoles'

Minera Tizapa mine had been resolved by the company

and the Mexican authorities, according to the Office of the U.S.

Trade Representative.

"Activating the Rapid Response Mechanism at the Minera

Tizapa mine not only allowed eleven unlawfully dismissed workers

to get their jobs back, but also ensured that they returned to a

changed environment free from employer interference and

discrimination," said U.S. trade chief Katherine Tai.
