After a long negotiation, the contract of Sino-Russian Natural-gas Supply via the Eastern Gas Pipeline was finally signed, which also benefited greatly from the Ukraine situation. As required in this contract, gas transmission began from 2008 and then gas de-livery capacity should be increased year by year;from 2023, the an-nual capacity will reach 380×108m3;and the total cost is over$400 billion during the 30-year contract period. However, industry figure thinks whether the adequate gas supply will be on time or not is still uncertain. Increasing the mutual trust, seeking the common ground, and seizing the good chance could be the key terms to a successful negotiation without any doubt. If the bilateral relationship may de-velop further to make the phase two of gas transmission via both eastern and western pipelines into shape and to let the gas delivery capacity of Middle Asia grow, the annual capacity from the north and the west is going to be 1 500×108 m3 around 2030. All changes happened on global oil and gas supply and marketing structure make a contribution to China’s oil and gas import. Meanwhile, they also urge Russia to make more efforts to export oil and gas to East Asia. Owing to gradual increase of Sino-Russia oil and gas trades, their overall strategy partnership will improve immeasurably.
