After beginning 2018 with Twitter attacks on Pakistan and Iran, the US leader has turned his attention to old foe Kim Jong-un.
He wrote: “Sanctions and other pressures are beginning to have a big impact on North Korea. Soldiers are dangerously fleeing to South Korea.
“Rocket man now wants to talk to South Korea for first time. Perhaps that is good news, perhaps not – we will see!”
The tweet comes after Kim Jong-un suggested he was willing to work to bring an end the tensions on the Korean peninsula and open a dialogue with South Korea.
With the Winter Olympics in South Korea fast approaching, the North Korean leader appeared keen to improve ties with his neighbours in the South.
He said the North and South could meet urgently to discuss the North sending a delegation.
The leader added: “The Winter Olympic games that will be held soon in the South will be a good opportunity to display the status of the Korean nation and we sincerely wish that the event will be held with good results.”
Meanwhile Kim Jong-un’s New Year address gave no indication that the hermit nation is planning to give up its nuclear and missile programmes, with the dictator warning Donald Trump he has a “nuclear button” on his desk.
He told the nation: “We must mass-produce nuclear warheads and ballistic missiles and speed up their deployment.
“We should always keep readiness to take immediate nuclear counter-attacks against the enemy’s scheme for a nuclear war.
“The US should know that the button for nuclear weapons is on my table. This is reality, not a threat.
“The entire area of the US mainland is within our nuclear strike range. The United States can never start a war against me and our country.”
