Anti-China protests have erupted in New Delhi as heads of state and senior ministers of the top five emerging nations gather for their annual summit.

Tibetan protesters clashed with police outside the New Delhi conference hall as delegates to the BRICS (Brazil, Russia, India, China and South Africa) summit, including Chinese President Hu Jintao, gathered to discuss their economic pact.

The leaders were attending the fourth summit meeting. The focus this year is on global governance and sustainable development.

Brazil's President Dilma Rousseff, Dmitry Medvedev of Russia, Hu of China, Jacob Zuma of South Africa and India's Prime Minister Manmohan Singh are at the summit.

But it was overshadowed by the self-immolation of the Tibetan exile Jamphel Yeshi who burnt himself to death in protest against the participation of Hu because of China's submission of Tibet. Protests have been continuing as delegates talk.

India is home to 100,000 Tibetan people who are living in exile.
