Depends on how you look at it.

Explanation:

Nixon opening up relations with communist countries was very good in terms of opening trade with low wage labor economies like china which represented a big economic success for both America and China. Him opening up relations improved Americas standing with many nations of the world including the soviets leading to reduction of nuclear arms in the future, these are positive aspects to it. The negative aspect is that mutual benefit also helps communist adversaries of America, opening up liberal trade with china failed to bring democracy to China, in fact it only led to higher levels of authoritarianism and shady economic practices like currency manipulation which hurts American currency exchange value. Its complicated, i would personally say it was a good idea but with a few major drawbacks geopolitically.
