I'm no foreign policy expert, but when Nixon wanted to visit Mao, he shouldn't have had to go through all those complicated shenanigans. He should have just picked up the durn phone and said, "Yo, Mao my man, let's get together. Chat about stuff. You know, nothing big. It's just that we haven't talked in a long time (the US and China, that is). I'll hop on my plane and roll in to Beijing tomorrow. Sound good?"
