The North Korean contributions to the Chinese Communist victory were not forgotten after the creation of the People's Republic of China in 1949. As a token of gratitude, between 50,000 and 70,000 Korean veterans that served in the PLA were sent back along with their weapons, and they later played a significant role in the initial invasion of South Korea. China promised to support the North Koreans in the event of a war against South Korea. The Chinese support created a deep division between the Korean Communists, and Kim Il-sung's authority within the Communist party was challenged by the Chinese faction led by Pak Il-yu, who was later purged by Kim.

When it comes to civil and criminal cases, the Bundesgerichtshof is at the top of the hierarchy of courts. The other branches of the German judicial system each have their own appellate systems, each topped by a high court; these are the Bundessozialgericht for matters of social security, the Bundesarbeitsgericht for employment and labour, the Bundesfinanzhof for taxation and financial issues, and the Bundesverwaltungsgericht for administrative law. The so-called Gemeinsamer Senat der Obersten Gerichtshöfe (Joint Senate of the Supreme Courts) is not a supreme court in itself, but an ad-hoc body that is convened in only when one supreme court intends to diverge from another supreme court's legal opinion or when a certain case exceeds the authority of one court. As the courts have well-defined areas of responsibility, situations like these are rather rare and so, the Joint Senate gathers very infrequently, and only to consider matters which are mostly definitory.

In 2002, Chinese geologist Chen Xuezhong published a Seismic Risk Analysis study in which he came to the conclusion that beginning with 2003, attention should be paid to the possibility of an earthquake with a magnitude of over 7.0 occurring in Sichuan region. He based his study on statistical correlation. That Sichuan is a seismically active area has been discussed for years prior to the quake, though few studies point to a specific date and time.
