MOSCOW - North Korean Foreign Minister Choe Son Hui arrived in Russia's far eastern city of Vladivostok on Tuesday and will visit Moscow on Wednesday, Russian state media said.

       Choe arrived one day after NATO said North Korean military units had been deployed to Russia to support its war with Ukraine. Russian President Vladimir Putin has not denied the presence of North Korean troops in the country.

       Russian state news agencies said it was not clear who Choe, who is visiting for the second time in six weeks, would meet in Moscow.

       The Pentagon on Monday estimated 10,000 North Korean troops had been deployed to eastern Russia for training, up from an estimate of 3,000 troops last Wednesday.

       Putin has said it is Russia's business how to implement a partnership treaty he signed with North Korean leader Kim Jong Un in June, under which the two countries agreed to support each other if one of them came under attack. REUTERS
