North Korean leader Kim Jong Un has arrived in Russia for his summit with President Vladimir Putin in the Pacific port city of Vladivostok.

Russian news agency Tass quoted a local official as saying Kim was given flowers, bread and salt at the Hasan train station after crossing the border.

Kremlin adviser Yuri Ushakov told Russian media Tuesday that the summit Thursday will focus on North Korea's nuclear program.

Kim's Russia trip comes about two months after his second summit with President Donald Trump failed because of disputes over U.S.-led sanctions on the North.

The state-run Korean Central News Agency said Kim was seen off by officials and residents as he left Pyongyang by his special train at dawn Wednesday.
