MEXICO CITY, May 25 (Reuters) - French tire maker Michelin resumed operations at its two plants in Mexico on Monday, saying that activity will be staggered at first.

The Mexican government's decision to classify the automotive industry as an essential activity made it possible to restart operations, Michelin said in a statement.

The company, which reported an 8.3% drop in first-quarter sales worldwide, said it will resume operations in Mexico "based on production demand." (Reporting by Adriana Barrera; Editing by Richard Chang)
