Although Chinese investors have complained about their sometimes frustrating experiences in India, they hope for a bright future for their investments in one of the fastest-growing markets with huge potential, reports Gao Changxin in New Delhi

Standing next to a giant drilling machine 40 feet underground in downtown New Delhi, Lu Yuanqiang is dripping with perspiration, frustrated that his state-of-the-art machine can't drill one inch further though everything is ready.

Lu is in charge of the Indian business of Chinese constructor Shanghai Urban Construction Group Corp, which won a contract to build part of the tunnel for a new 9.37-km subway in downtown New Delhi.
