BEIJING/NEW DELHI (Reuters) – General Motors (GM.N) aims to grab at least 5 percent market share in India within the next decade, as it sees that market overtaking Japan as the world’s third biggest with projected annual sales of 8 million vehicles by 2025. The Detroit carmaker, which is losing money in India even after 18 years there, will unleash a product blitz aimed at reviving sagging sales, and will make India a new global manufacturing and export hub, taking some of the strain off South Korea, where labor costs have ballooned in recent years.
