This study explains what will be the best policy of Park Geun-hye administration for China(People's Republic of China) in the era of G2(Group of Two). G2 is a proposed informal special relationship between the United States and China. Originally initiated by C. Fred Bergsten as primarily an economic relationship, it began to gain wider currency and scope from foreign policy experts as a term recognizing the centrality of the U.S.-China relationship near the beginning of the Obama Administration. As the two most influential and powerful countries in the world, there have been increasingly strong suggestions within American political circles of creating a G2 relationship where the United States and China would work out solutions to global problems together. One possible reason for the G-2 to possibly be created is to prevent another Cold War. The informal G2 has been considered as helpful in finding solutions to the global financial crisis, North Korea's nuclear program, nuclear non-proliferation and nuclear disarmament, etc. Nuclear weapons in North Korea impose an enormous threat, not only to peace on the Korean Peninsula but the entire world. As a realistic policy, Park must ask China to urge North Korea to abandon its nuclear ambitions.
