NEW DELHI (Reuters) - Commerce Secretary Gary Locke said on Monday he was concerned about India's tariff, non-tariff barrier in bilateral trade relations.

Locke's remarks came after a meeting with Indian Trade Minister Anand Sharma.

Despite India's growing global weight, it is only the United States' 14th biggest trading partner and obstacles, from outsourcing controversies to the Doha world trade round and market access, have put the brakes on faster integration.
