India's Prime Minister Manmohan Singh is travelling to China, as the two countries look to boost economic ties.

In December, the two countries agreed to increase bilateral trade to $100bn (£66bn) by 2015, up from $60bn in 2010.

Mr Singh will also attend a summit in China that will include Brazil, Russia, India, China and South Africa.

China is India's largest trading partner. However, the two countries still share a very unbalanced trade relationship.

"India's import dependence on China has gone up significantly on critical items," said Samiran Chakraborty, regional head of research for India at Standard Chartered Bank.

"Whereas if you look at exports, India's primary export to China is only iron ore."

Mr Chakraborty says this issue could come up during the visit.

"One of the demands is to open up the Chinese markets to India. Otherwise the trade balance is very much in favour of China and working against India," he adds.
