South Korea should not shake alliance with U.S. by favoring China too much

From The Yomiuri Shimbun:

It is vital that the United States and South Korea maintain their solid alliance, for the deterrence of North Korea’s military provocations and the regional stability of Asia. South Korea should not weaken these ties by getting too close to China.
U.S. President Barack Obama held talks with his South Korean counterpart Park Geun-hye in Washington and they adopted a joint statement focusing on their cooperation to get Pyongyang to abandon its nuclear and missile programs.
The statement warns that additional sanctions will be imposed on Pyongyang should the country push through with launching a ballistic missile or conducting a nuclear test in violation of U.N. Security Council resolutions.
