South Korea said Friday it believes Pyongyang remains committed to improving relations despite strongly criticizing Seoul over ongoing US-South Korean military drills and insisting it will not return to talks unless its grievances are resolved, AP reported. South Korean Unification Ministry spokesman Baek Tae-hyun said Seoul expects North Korea to faithfully abide by the agreements between its leader, Kim Jong-un, and South Korean President Moon Jae-in at their summit last month. The leaders issued a vow on the “complete denuclearization” of the peninsula and pledged permanent peace. “We are just at the starting point and we will not stop or waver as we move forward for peace in the Korean Peninsula,” Baek said. North Korea has taken verbal shots at Washington and Seoul since canceling a high-level meeting with South Korea on Wednesday and threatening to scrap next month’s planned summit between Kim and US President Donald Trump.
