"The goal of our government is to strive for [a formal end of the war] this year," Kang said, as quoted by the Yonhap news agency.
In April, Kim Jong-un held a historic summit with South Korean President Moon Jae-in and agreed to jointly work on peacefully resolving long-standing bilateral tensions.
Recently Moon Jae-in expressed hope that the US-North Korean high-level summit will pave the wave for an "era of complete denuclearization" and peace in the region, after Donald Trump and Kim Jong-un met on the Singaporean island of Sentosa and signed a document showing their commitment to establish new bilateral relations and build a lasting peace on the Korean Peninsula.
