Which is more important – the deployment of the U.S. missile defense system called Terminal High Altitude Area Defense (THAAD) or the huge investment from China?

This might be a dilemma for Korea.

Currently, China is South Korea's largest trading partner as well as the largest source of foreign tourists and China might soon become South Korea’s biggest foreign investor.

South Korea should have regards to China’s feeling before making any political move.

Besides, South Korea is weighing on establishing a gas pipeline that runs between South Korea and China which will see further integration of the economies between the countries.

The decision to be made by President Park Geun-hye is particularly important in light of the current situation.
