Chinese president Xi Jinping may have met with a high-ranking North Korean official in the Chinese port city of Dalian amid tight security, according to media reports after a North Korean airliner was spotted at the city’s airport.
South Korea’s Yonhap News Agency said North Korean leader Kim Jong Un may have been aboard the plane, although it cited no direct evidence.
Japan’s Kyodo News service said the plane had departed on Tuesday.
Hong Kong’s South China Morning Post newspaper cited two unidentified sources as saying that Xi had flown to Dalian on the coast east of Beijing to meet with the official as well as to preside over the official launch of sea trials for China’s first entirely self-built aircraft carrier.
Chinese internet users posting on social media described heavy security in the city and extensive flight delays on Monday. Others said they spotted a set of Red Flag limousines used by state leaders.
He is expected to meet US president Donald Trump for a historic summit, possibly by the end of this month.
Yonhap said a North Korea plane arrived on Monday amid tight security. Japanese broadcaster NHK ran a picture of an Air Koryo plane that it said had been taken on Tuesday afternoon at Dalian’s airport.
There are no regularly scheduled flights between North Korea and Dalian.
China is North Korea’s only major ally, although trade has plummeted in recent months as Beijing enforces United Nations economic sanctions in response to the North’s nuclear bomb and ballistic missile tests.
Chinese foreign ministry spokesman Geng Shuang told reporters Tuesday that he had “no information to offer at this moment”.
“China and North Korea are close neighbors and always maintain normal communication and exchanges with each other,” Mr Geng said.
