MOSCOW, Sept 2 (Reuters) - Russia's Gazprom

and China National Petroleum Corporation signed an agreement to

increase annual gas supplies to China via the Power of Siberia

pipeline as well as via the Far Eastern Route, Russia's RIA

agency reported on Tuesday.

Reuters reported last month that China was seeking to buy

more Russian gas through an existing pipeline as talks between

the two countries have failed to make progress on building a

second link.

The agreements were signed during Russian President Vladimir

Putin's visit to China where he is due to attend a military

parade on Tiananmen Square on Wednesday marking the end of World

War Two after Japan's formal surrender.

RIA, citing Gazprom's CEO Alexei Miller, said that Gazprom

and CNPC have agreed to increase supplies to 44 billion cubic

metres (bcm) a year from 38 bcm a year.

Additionally, the two have agreed to increase gas supplies

via the Far Eastern route to 12 bcm from the 10 bcm.

Miller also said that a legally binding memorandum has been

signed for the construction of the Power of Siberia 2 pipeline

to China and the Soyuz Vostok transit gas pipeline through

Mongolia.

"Gazprom and CNPC also signed today a new memorandum on

strategic cooperation, which reflects a new stage in our work

with CNPC on new projects," Miller said.
