LIMA, May 18 (Reuters) - Iron output from the Peru unit of Shougang Group Co Ltd was halted on Monday as the union called a national strike, seeking stronger labor laws for mining workers, union leader Julio Ortiz said.
Ortiz said all 963 workers at the mine took part in the strike and the company did not deploy contract workers to replace them.
Unions at several mines in Peru had planned to take part in the national strike that started Monday.
Shougang' Peru mine produced 7.2 million tonnes of iron last year. (Reporting by Mitra Taj; Editing by Jeffrey Benkoe)
