Chinese Vice Premier Zeng Peiyan has called for expanded international cooperation in controlled nuclear fusion development.

Controlled nuclear fusion could be a viable solution for the world's energy supply, said Zeng in a letter to the ongoing 21st International Atomic Energy Agency (IAEA) Fusion Energy Conference.

It is seen as an efficient way for people to generate infinite and clean energy, said Zeng, and China has been actively promoting nuclear fusion development.

Zeng said China expects to join the international community in conducting research in this field and pushing for the sustainable development of the world.

More than 800 scientists from around the world are attending the six-day conference that kicked off on Monday.
