Nixons overseas trips, post presidency

I’ve never heard what the purpose of his trips were. I always assumed they were political.
With all this effort to raise Reagan to godlike status, me thinks they are premature, I’m wondering where Regan got all the information needed to be so “great”
I’m not a Nixon or Reagan fan but I’m thinking someone that had the political clout of Nixon would be quite helpful in fashoning foreign policy.

There doesn’t appear to be a factual question here, so I’ll close this thread.
