Nope. That’s not really possible and not how gas works. Russia has limited capacity to export gas to China - it has one pipeline from a smaller gas field. There’s no way to export gas to China from its bigger gas fields - would take a decade of work at a minimum to get gas to China. It has minimal LNG export capacity - which is how it would get around its lack of pipeline infrastructure if it had its s**t together, which it most certainly does not.
The Chinese are like the robot in Forbidden Planet and can manufacture anything you want in any quantities you want. Try youtube search on “chinese engineering projects”. A pipeline would not faze them.
