Is the comprehensive strength developed in China or South Korea?

Of course, comprehensive national strength depends not on per capita, but on the whole country.

Economically, China's GDP ranks among the top four in the world. The speed of economic development is even more unstoppable.

Politically, China has been a traditional big country and powerful country since ancient times, and it was not until the late Qing Dynasty that China declined. But now, China's prestige in the world and the region has been re-established. Why is the "Six-Party Talks on the Korean Nuclear Issue" held in Beijing? Why not hold it in Tokyo, Seoul, Washington or Moscow?

China's influence in the world is increasing day by day. How can we say that China's comprehensive national strength is inferior to that of South Korea?
