As an expert in international relations and geography, I can provide a comprehensive answer to your question.

Korea is not in Japan or China; it is a sovereign nation located in East Asia. The Korean Peninsula is situated in the northeastern part of Asia and is bordered by China to the west, Russia to the north, and Japan across the sea to the southeast. The peninsula is divided into two separate countries: North Korea (officially known as the Democratic People's Republic of Korea, or DPRK) and South Korea (officially known as the Republic of Korea, or ROK).

North Korea occupies the northern part of the Korean Peninsula, while South Korea occupies the southern part. Both countries were originally part of a single nation but were divided after World War II due to the political and military influence of the Soviet Union and the United States. The division was formalized with the establishment of separate governments in 1948.

The **China-Japan-South Korea trilateral summit**, as you mentioned, is an important diplomatic event that brings together the leaders of China, Japan, and South Korea. This summit is significant because it fosters dialogue and cooperation among these three major East Asian economies. The first summit took place in December 2008 in Fukuoka, Japan, and since then, it has been held annually to discuss various issues of mutual interest, including economic integration, regional security, and cultural exchange.

It's essential to recognize that while geographical proximity and historical ties influence the relationships between these countries, each maintains its own sovereignty and distinct identity. The trilateral summit serves as a platform to address common challenges and to enhance mutual understanding and collaboration.

In conclusion, Korea is not a part of Japan or China but is a separate nation with its own unique culture, history, and political system. The trilateral summit between China, Japan, and South Korea is a testament to the importance of regional cooperation and the recognition of each country's sovereignty and interests.
