When meeting with Russian Prime Minister Vladimir Putin after the seventh round of the Sino-Russian energy negotiators' meeting, Wang said China hopes the two sides could make further essential progress in gas talks as soon as possible.

This year marks the 10th anniversary of the Treaty of Good-Neighborliness and Friendly Cooperation between China and Russia.

At the latest energy talks, the two sides exchanged views and plans on future energy cooperation, demonstrating mutual trust as well as candid and pragmatic spirit of cooperation between China and Russia, he noted.

Wang and Russian Deputy Prime Minister Igor Sechin inked a protocol to the Sino-Russian gas cooperation memorandum of understandingn Tuesday.

Putin said the two countries have jointly overcome the impact of global financial crisis on their bilateral trade, as the trade volume has reached $18 billion in the first quarter and would climb to $70 billion at the end of this year.

He stressed that energy cooperation plays an important role in boosting the Sino-Russian strategic partnership of coordination, and Russia is glad to see the two countries' joint efforts in such areas as oil, gas, coal, nuclear energy, electricity and renewable energy.

Following the Sino-Russian oil pipeline project, which was put into operation on January 1, the two countries are now negotiating two long-term gas projects, Putin said.

These projects, with the "west line" capable of supplying to China 30 billion cubic meters of natural gas and the "east line" of 38 billion cubic meters every year, would both be 30-year deals, the Russian PM said.
