Recently, according to Yonhap News Agency, Bank of Korea announced the renewal of the currency exchange agreement with the People's Bank of China. The agreement is extended for three years and the scale has reached US$ 56 billion, the same as the previous agreement. Anbound believes that the renewal of the currency exchange agreement between China and South Korea is an important indication of the relationship between the two countries; if this "window" is closed, that would mean the previously intimate economic relations between the two countries will continue to deteriorate; on the other hand, if this “window” remains open, then the two countries are willing to retain the communication channel. Korean media disclosure of the results are in line with our proposed direction.
