After China surpassed Japan in terms of nominal GDP, China will engage more in South-South cooperation, said Haruhiko Kuroda, president of Asian Development Bank (ADB).

Kuroda made the statement at a press conference under the 44th annual meeting of the Board of Governors of the ADB in Vietnam's capital city of Hanoi Tuesday.

In 2010, China's GDP was valued at near 5.8 trillion U.S. dollars, surpassed Japan's 5.47 trillion U.S.dollars and became the world's second largest economy after the United States.

Kuroda said China's population is 10 times more than that of Japan, which is an advantage of China's economy. "China surpassed Japan to become second largest economy, but Japan still remains a modern economy," he said.

In the past few decades, China has been become a phenomenon in reducing poverty, improving living standards of people and particularly providing more better infrastructure, Kuroda said. China is expected to play more construction role in Asia's economy and South-South cooperation, to contribute more to the economic growth of the region and the world, said Kuroda.
