"India's trade deficit with China is expanding. In the short term, that's hard to resolve. The imbalance is mainly because India has limited exports to China, while Chinese manufactured goods have a competitive advantage in the Indian market," Liu Xiaoxue, a researcher on South Asian studies at the Chinese Academy of Social Sciences said.
The slower growth pace in China in recent years, together with overcapacity in the steel and iron sectors and the Chinese government's tightening policies in the real estate sector, reduced demand for Indian raw materials - mainly iron ore and iron sand, which account for the bulk of Indian exports to China.
In the first four months of the year, Sino-India trade declined 6.2 per cent year-on-year. Chinese exports increased 3.6 per cent and imports decreased 24 per cent, yielding a trade surplus of USD 8.83 billion, according to China's General Administration of Customs.
In 2012, bilateral trade dropped 10.1 per cent, and China's exports went down 5.7 per cent while its imports plunged 19.6 per cent, leaving a trade surplus of USD 28.87 billion, compared with USD 27.17 billion in 2011 and USD 20.08 billion in 2010, according to customs data.
"The trade imbalance is rooted in India's trade structure. India's trade deficit with China will not be reversed in the foreseeable future. Any change depends on whether India can export products that meet the demand of the Chinese market," Hu Shisheng, director of the Institute of South and Southeast Asian and Oceanian Studies at the China Institutes of Contemporary International Relations said.
