Hu said in his statement that the international situation is currently undergoing complicated and profound changes while the recovery of world economy is yet to find a solid foundation.
"Under such circumstances, it's of great significance for the leaders of the BRIC countries to get together again for converging consensus and strengthening cooperation so as to better deal with global challenges," Hu said in the statement.
"I wish the second official meeting of the leaders of the BRIC countries a complete success," Hu said.
The summit gathers Hu, Lula, Russian President Dmitry Medvedev and Indian Prime Minister Manmohan Singh. Hu will make a speech at the meeting and hold separate meetings with leaders of other countries.
In a telephone call with Lula in February, Hu said the four BRIC countries share the same or similar opinions on many global issues and have great potential in bilateral and multilateral cooperation.
Hu said China attaches great importance to the cooperation platform of BRIC countries and is willing to strengthen communication and cooperation with Brazil, Russia and India.
The first summit of the BRIC countries was held in Yekaterinburg, Russia in June 2009.
