Japan and India are to study ways to introduce energy-saving technologies in India.

Japanese trade and industry minister Akira Amari met with deputy chairman of India's planning commission Montek Singh Ahluwalia on Monday in Tokyo, where they hammered out a commitment to step up cooperation on energy issues, including sending Japanese experts to India to introduce energy-saving technologies.

Japan has also held ministerial-level dialogues on energy issues with China.

As India and China refused to ratify mandatory cuts in emissions in the 1997 Kyoto protocol, which expires in 2012, the US and Australia rejected the treaty on similar groups, saying it would unfairly disadvantage their economies.

Japan is to invest in India's energy industry and transfer energy-saving technology.

Both China and India are two of the world's fastest growing economies.

Japanese leader Shinzo Abe is meeting US counterpart George Bush this week in Washington, where they are expected to discuss a joint strategy to reduce global warming, including the building of more nuclear power stations.

Meanwhile, Japan, home to the world's second biggest economy, will host next year's G8 summit in the area of Lake Toya in the northernmost main island of Hokkaido.

Analysts said Mr Abe backed Lake Toya to convey his 'beautiful nation' message.

Mr Abe believes environmental issues will be key topic at the summit.
