To be fair, the Korea War was a learning experiences for both the US Army and Chinese Army.
The bravery, sacrifice and tactics of CPVA were underestimated and not expected by the US Army. They did not have the experience of dealing with such an enemy before. But the US Army was able to regroup after the initial setbacks and learned the weakness of the CPVA (weekly offense, for example). They became better and were able to hold the line later during the war.
The Chinese Army did perform way above everyone's expectations. But they also learned that the US Army was not Nationalist Army or even Japanese Army. The air power and logistic support were particularly impressive. The US Army's morale in general was low compared to the CPVA, but they did demonstrate their discipline even during retreat. The Korea War experience influenced how PLA developed itself later. It was the first time the Chinese military fought a large-scale modern war against a world-class opponent. The PLA Air Force was born out of Korea War, for example. The CPVA were also much better equipped later during the war due to the Soviet Union support.
There were respects from both sides to the other side. In the end, both sides lost appetite to continue the fight - it didn't make much sense any more when there were other higher priorities elsewhere.
