I believe you are mistaken, comrade. I am not actually Nikita Khrushchev nor am I Mao Zedong. Any "double-standard" you see with Deng Xiaoping's Reform and Opening Up as a result of problems with the late Mao era and the Gang of Four must be considered from that context, and not merely from one aspect of Mao's critique of Khrushchev's policy before the Gang of Four era.
Regarding the Gang of Four, they were largely an extension of Mao's incorrect lines towards the end of his life, without most of his positive lines. Deng Xiaoping corrected the course for the new era of development, having inherited a basically industrialized economy but with widespread poverty and backwards technology.
As for China outmaneuvering the west, I agree. This is pretty plainly what happened, despite what the west thought they could get away with, China maintained a dictatorship of the proletariat and maintained political control in the socialist market economy.
