Trump had said that North Korea changed its approach towards the summit after Kim had his second meeting with President Xi Jinping in China.
The US president said the lines of communication had opened between the two countries after Trump administration officials on Thursday said that the North Koreans had become unresponsive, leading to the planned summit's cancellation.
On June 12, history was made when United States President Donald Trump shook hands with North Korean leader Kim Jong-un and had extensive talks at Capella Hotel in Singapore. However, this meet has come after several twists and turns. Following is the chronology of key events leading to a historic summit between the two leaders.
