South Korea's presidential office said Thursday it is seeking to figure out the background of U.S. President Donald Trump's abrupt cancellation of his agreed-upon summit with North Korea's leader Kim Jong-un.

"(We) are trying to figure out what President Trump's intention is and the exact meaning of it," Cheong Wa Dae spokesman Kim Eui-kyeom told reporters. (Yonhap)
