MOSCOW, May 18 (Reuters) - Russian President Vladimir Putin will discuss all areas of bilateral relations with Chinese President Xi Jinping on a visit to China this week, including the proposed Power of Siberia 2 gas pipeline, a Kremlin aide said on Monday.
Putin will arrive in China on Tuesday evening and meet with Xi on Wednesday morning, the aide, Yuri Ushakov, told reporters. The Russian delegation will include senior officials and heads of large companies, including oil producer Rosneft and gas firms Novatek and Gazprom.
The proposed Power of Siberia 2, long under discussion, could one day deliver an additional 50 billion cubic metres (bcm) of gas per year from Russia's Arctic gas fields via Mongolia to China.
Ushakov said close ties between Moscow and Beijing were increasingly important, given global crises. Russia boosted oil supplies to China by more than a third to 31 million metric tons in the first quarter of this year, he said.
The Kremlin chief's trip to China comes on the heels of U.S. President Donald Trump's own visit there last week, but Ushakov said the timing of the visits was a coincidence.
