A Chinese official lodged a complaint with South Korea's ambassador to China, in a tit-for-tat move after Beijing's envoy to South Korea was summoned last week over his comments accusing Seoul of tilting toward the United States.
Assistant Foreign Minister Nong Rong expressed dissatisfaction with Seoul's response to last week's meeting between Chinese Ambassador Xing Haiming and a South Korean opposition leader, according to a statement Sunday from China's Foreign Ministry.
