MEXICO CITY (Reuters) – Auto parts supplier Bosch is planning to invest $146 million to expand its plant in the central Mexican state of Queretaro, where it will install new high-tech production lines and open a 12,000-square-meter warehouse, it said on Thursday. The world’s largest supplier of auto parts last year announced investments of at least $174 million for other factories in Mexico, where Bosch has more than a dozen sites and employs 17,200 people.
