It is consistent with the common interests of the two sides to establish an international energy order, which is fair, equitable, secure and stable, and to the benefit of the entire international community.

China and India will strive for bilateral and international co-operation to diversify the structure of global energy and to increase the share in it of renewable energy sources, it said.
