When there is a historic meeting between North and South Korean leaders - many have raised a question - it was possible that finally - who is its credit?
Some claim that Donald Trump and the South Korean President agree that the credit for negotiating peace with North Korea deserves the Donald Trump.
In response to this, many people say that what has affected this discussion will only be seen from historical documents, but there is evidence from the fact that South Korea encouraged negotiations with the North, with China's imposed sanctions pressure.
But Donald Trump himself said that he would take credit for the change in the Korean peninsula long ago.
On 4th of January this year, Donald Trump tweeted, 'False' experts' - talking about it a lot. But if I did not take a tough stand and did not disclose the promise of full power against North Korea - would anyone believe that this dialogue would have been discussed?
South Korean President Mon Zaye-In also openly said that the answer to this peace is to get big credit in the President Trump.
This is possible because of his 'US-led sanctions and pressure'.
In May or June this year, Donald Trump is expected to hold a meeting with North Korean leader Kim Jong-an - which will be the first meeting of a US president with a North Korean leader.
Maybe this discussion will reduce the tension in the Korean peninsula, a peace treaty can be done to end the 68-year-old Korean War.
North Korea caused their first experimental nuclear explosion in 2006.
Since then, the United Nations has imposed a number of trade sanctions on North Korea - many of which are proposed in the US These restrictions have become tougher and tougher since then.
But the worst hit North Korea is the change in China - because 90 percent of the North Korean trade is with China.
Earlier, China had rarely applied UN sanctions. But since last year, China has been considered to implement these restrictions.
President Trump tweeted this January 2, that Kim Jong Un said that his desk always had a nuclear button, would anyone tell the ruler of the country who did not eat this food that I also have a nuclear button which is much larger, more powerful?
Mr. Before the trump, two President Barack Obama and George Bush also talked about military action against North Korea. On the other hand, some of South Korean's former presidents have a strong policy regarding North Korea and others talk about negotiations. Two South Korean leaders have met with the leader of the northern region.
It was a significant event to present North Korean athletes at the Winter Olympics during the current President Moon Zayen and parade under a flag.
Why South Korea is giving credit to the President Trump?
Dr. Euston University Virginia Grechchik says South Korea has worked strategically.
They wanted to create a dialogue for Americans, because at some point in Korea, America was somewhat riddled by the American policy and was concerned.
