SEOUL (Reuters) - North Korea's foreign minister Ri Yong-ho told his South Korean counterpart Kang Kyung-wha in a meeting on Sunday that Seoul's proposal to improve ties with the North "lacks sincerity", the South's Yonhap News Agency reported on Monday.


The two were speaking on the sidelines of a days-long event by foreign ministers in Southeast Asia that has been taking place since the weekend, Yonhap said.


South Korea's foreign ministry was not immediately able to confirm the report.
