:: US President Donald Trump said on Tuesday that possible talks between North Korea and South Korea held mixed potential, while sanctions were beginning to take a toll on Pyongyang amid tensions over its nuclear and missile programs.

“Sanctions and ‘other’ pressures are beginning to have a big impact on North Korea. Soldiers are dangerously fleeing to South Korea,” Trump wrote in a post on Twitter.

“Rocket man now wants to talk to South Korea for first time. Perhaps that is good news, perhaps not – we will see!” Trump added in reference to North Korean leader Kim Jong Un.

Trump’s tweets come in light of South Korea offering high-level talks with rival North Korea on Tuesday to find ways to cooperate on next month’s Winter Olympics in the South.

Seoul’s quick proposal following a rare rapprochement overture from the North a day earlier offers the possibility of better ties after a year that saw a nuclear standoff increase fear of war on the Korean Peninsula.
