Here are some basic relations:

Japanese and Korean Relations: Both Koreas and Japan have a very poor relation.

China and North Korea: They are on good terms and the Council on Foreign Relations described China as "North Korea's most important ally, biggest trading partner, and main source of food, arms, and fuel"

China and South Korea: During World War 2 Japan had committed many war crimes in both the People's Republic of China and causing both countries to oppose Japan's current government.

China and Japan: The two countries were both on opposing side during WWII and China actually joined the Allies on December 9th, 1941, 2 days after the Attack of Pearl Harbor. The Chinese civil war broke out but was interupted after the Second Sino-Japanese War. The countries a currently trying to improve their relations.

Also note North and South Korean Governments are different, that also is why Korea split into two. Northen Korea has a Juche republic government and South Korea has a Presidential republic government.

Well Superpowers have a tendancy not to get along. Russia, China and Amercia (U.S) are the three current superpowers. Though America may not continue to be the most powerful nation due to the current poor government and economy, in that case in which China has a possibility of becoming the most powerful nation.

Sorry about the long post..... P.S I agree with FluffySkies95 on the first part. Good Job, you're also really good at expressing yourself on writing. ;)
