This is frequently stated as a goal of the 5D chess but it is ridiculous if you think about it. China is not buying oil and gas from Russia at discount rates (and had been for quite a while). They haven't performed blood rites with Venezuela that force them to only get oil from Venezuela. They can buy it from anybody who is willing to sell. Even if you sink the Middle East into the ocean they will still be able to buy oil from others, albeit at much higher prices. So no, this is not a strategic target, unless you actually want to attrition them to bankruptcy with oil prices. But this path is and should be very unpopular with regular citizens.
