Beijing: India-China bilateral trade hit a record USD 73.9 billion last year, but the ballooning trade deficit in Beijing's favour rose to over USD 27 billion, raising concern among Indian authorities.

The bilateral trade registered a USD 12.2 billion increase in 2011, taking the total to USD 73.9 billion as against USD 61.7 billion in 2010, according to official trade figures for the last year.

The trade deficit in 2011, however, piled up to USD 27.07 billion even though Indian exports to China went up to USD 23.4 billion registering a growth of almost 12.26 percent compared to the same period in year 2010.

"The overall trade figure looks good but the deficit remains a cause for concern," Indian Ambassador to China S Jaishankar said.

He said efforts are being made to improve market access for Indian products in China.

"We have some early signs of movement in access to the Indian IT products. But these are early days," he said, referring to various campaigns organised by the Indian Embassy to push IT and Pharmaceutical exports to China.

Most important thing is that the bilateral trade is growing well despite the global economic downturn, he said.

Chinese officials have been acknowledging India's concerns over trade deficit and the issue was expected to figure in detail in India-China Trade Ministers talks during the BRICS Commerce Meeting on March 28 in New Delhi.

The Indian exports, mainly composed of primary products and commodity sector, increased despite the decline of iron ore exports, which dominated exports to China for long due to ban on mining in Karnataka and Goa, said K Nagraj Naidu, head of the economic and trade wing of the Indian Embassy.
