Bheki Langa made his remarks before President Xi Jinping's visit to South Africa. The countries mark 15 years of diplomatic ties this year.

The ambassador said his country is looking forward to Xi's visit and is honored by it. Xi visited South Africa in 2010 as vice-president.

The president will attend the fifth BRICS summit in Durban on Tuesday and Wednesday.

The countries that make up BRICS, an organization of emerging economies, are Brazil, Russia, India, China and South Africa.

Langa said the BRICS summit will cover the promotion of African infrastructure development, and the establishment of a BRICS-led development bank, think tank and business council.

Since "the Rainbow Nation" was admitted to the group in 2011, South Africa has brought its own experience and perspective to the BRICS with its unique history and independent foreign policy, he said.

South Africa's potential, combined with the economic power of the other members, will "enable the BRICS grouping to pave the way for a new global pattern" focusing on emerging economies, he said. Langa added that his country is working closely with China and other members of BRICS to advance the role of developing countries in international relations, and "ultimately to help fashion a more equitable global political and financial architecture".

Xi said before his trip that China supports the South African presidency's prioritizing of ideas such as the establishment of a BRICS development bank. He added that the development of cooperation between the BRICS facilitates the formation of a balanced world economy and democratic international relations.

China has become South Africa's largest trading partner both as an export destination and as a source of imports since 2008. Langa said his country is the destination for 25 percent of Chinese exports to the African continent and the source of 38 percent of Chinese imports from the continent.
