Alexander Matsegora, Moscow’s envoy to North Korea, cautioned Donald Trump not to place any further sanctions on Kim Jong-un surrounding “supplies of oil”.
He warned: “If the supplies of oil and oil product are stopped, it would mean a complete blockade of the DPRK (North Korea).”
He added that such an action would “be perceived as a declaration of war with all its consequences”.
The current UN sanction that caps oil supplies to 540,000 tons from China and 60,000 tons of refined oil from other nations was labelled as “a drop in the ocean”.
China is the biggest trade partner of Kim Jong-un – the recent UN sanctions saw trade between the two nations slashed in half.
Mr Matsegora recently explained that Russian specialists told him that Kim Jong-un was massively increasing his military might and that Donald Trump should think twice before making good on his promise to deliver “fire and fury”.
He went on: “It can be said that the North Koreans have managed to achieve a serious improvement in their missile program over the past year.”
Donald Trump’s increasingly aggressive rhetoric towards North Korea has led the US to push for increased sanctions to tighten the world’s grip on the aggressive nation.
Before Christmas, the UN Security Council unanimously voted to cut exports of gasoline, diesel and other oil products by 89 per cent.
At the time, Nikki Haley, the US ambassador to the UN, declared that “today, we cut deeper” as she explained that the provocative nation had “chosen the path of isolation”.
She added: “We will continue to match the Kim regime’s choice of aggressive action with actions of international sanctions.
“This most tragic example of evil in the modern world.”
President Donald Trump added the unanimous decision showed the “world wants peace”.
He tweeted: “The United Nations Security Council just voted 15-0 in favour of additional Sanctions on North Korea. The World wants Peace, not Death!”
