Your post is rubbish, you don't know what China plan is. Do you know what happens in the pacific? China has already started conquering Spratly Islands that belongs to Vietnam and Philippines, Senkaku that belongs to Japan. They already harassing/bullying with its powerful Navy. How much more if China gain more power. Without America, I'm sure China has already conquered Vietnam and Philippines.
China has longstanding territorial disputes over all those territories. And Senkaku is currently under the defacto administration of Japan. The PLA Navy is no match for the powerful Japanese navy. So you can't say that they are harassing. Either you don't know much details about the Japanese Navy, or you are seriously overestimating the capabilities of the PLAN.
China just recently taking the Philippine and Vietnam Islands and even using its aircraft carrier to bully this small countries. They already taken Scarborough Shoal, they are blocking the supply ship of the Filipino Navy. They demand the Filipino troops to leave the island. The island located less than 200 miles from Mainland Philippines and located more than 1500 miles away from China. This is fishing ground of the Filipinos since PreSpanish Time.
Don't think you Russians are safe from the Chinese. In the future when China is replacing USA as the sole superpower Russia will be the one of its priority to be conquered because if its natural resources. China is a Fascist country, and would not accept any nationality except Chinese. They are same like Hitler. They are waiting for the perfect time to conquer the world.
