Project 714 goes ahead...

Here's a link. Project 714 was the first Chinese manned spaceflight program, with a manned flight expected in 1973; however, it ended up being canceled.

They did manage to orbit the Dong Fang Hong satellite in 1970, the Cultural Revolution notwithstanding, so let's say that Project 714 goes ahead and China puts two men into orbit in 1973 and sees them safely return. What POD or combination of PODs would be necessary for that to occur, and what would the effects of such an event be?
 
Well to start with I'd assume the PRC would get help from the Soviets, so maybe no Sino-Soviet spilt?
