What's Japan going to do? Bomb its own Toyota, Sony, Hitachi, Panasonic, etc. factories that are popping up all over China? Japanese fear China economically more than Americans, yet Japanese are re-locating factories to China faster than anybody else, because capitalism is capitalism and Japan's competitiveness and Japan's vitality as a nation will suffer if Japan's factories don't move to China. Once China's economy grows as big as America's in 2-3 decades and twice as big in 4-6 decades, anybody who attacks the world's biggest economy will end up hurting their own economy more than China's. More than half of America's and Japan's entire stock market values and retirement funds will derive from their companies' business activities in China, and attacking China will be the best way for them to shoot themselves and their own people in the foot.

Well, predictions greater than a decade mostly fail. China very well MAY do so, but it will have a political change. If the change goes through smoothly, China will reach the levels you talk of. If there is a violent revolution or civil war, watch those stats tumble. Also, China, as a typical communist state, must be massaging the figures and putting up a nice shiny facade to the foreigners -- it does not allow anyone to see the real grimy face of China and communism.
