This energy corridor aims to bolster the natural gas supply in east China.

Once fully operational, the pipeline is expected to deliver 38 billion cubic metres of natural gas annually to regions including north-east China, the Beijing-Tianjin-Hebei area and the Yangtze river delta.

The pipeline spans 5,111km, with 3,371km of newly constructed sections.

It begins in Heihe, Heilongjiang province, and extends to Shanghai, serving as an essential energy route for eastern China.

The pipeline’s capacity is expected to meet the annual gas needs of 130 million urban households, alleviating supply constraints in these regions.

The east-route pipeline is projected to play a vital role in securing regional natural gas supply, supporting the development of a clean, low-carbon and efficient energy system, and promoting economic and social development.

In June 2024, talks between Russia and China over a major gas pipeline deal stalled due to disagreements over price and supply.

The negotiations involved the 2,600km-long Power of Siberia 2 pipeline, which runs from Yamalo-Nenets Autonomous Okrug in central Russia to Inner Mongolia in China.

In January 2024, Mongolia’s Prime Minister, Luvsannamsrain Oyun-Erdene, warned of delays in the construction of Russia’s mega-pipeline, which will connect the country’s western gas fields to China.

Oyun-Erdene had previously told the Financial Times that construction of the 3,550km pipeline, with 950km passing through Mongolia, was expected to begin in 2024.
