Russia's state-controlled gas giant Gazprom has inked a second long-term gas supply agreement with China National Petroleum Corporation (CNPC) with the goal of delivering up to 10 billion cubic metres of gas to the northeastern part of the country.

Though Gazprom has provided no details on the contract, Reuters quoted sources in Beijing as saying the arrangement will be valid for 30 years, with first deliveries to flow as early as the start of 2025.

Gazprom is finishing the upgrade of throughput capacity for an existing trunkline that runs from the Sakhalin Island to the Russian mainland in the far east of the country, passing cities of Komsomolsk-na-Amure and Khabarovsk and terminating in the Russian port of Vladivostok.
