WASHINGTON (AFP) - A commemorative coin featuring US President Donald Trump and North Korea's Kim Jong Un has been struck by the White House Communications Agency ahead of their planned summit next month.

The coin depicts Mr Trump and Mr Kim, described as North Korea's "Supreme Leader", in profile facing each other in front of a background of US and North Korean flags.

The words "Peace Talks" are emblazoned at the top of the front of the coin with the date "2018" beneath.

The back of the coin features a picture of the White House, Air Force One and the Seal of the President of the United States.

Mr Trump is scheduled to hold a landmark summit with the North Korean leader in Singapore on June 12, but Pyongyang has recently threatened to pull out over US demands for "unilateral nuclear abandonment."

The White House Communications Agency regularly issues commemorative or challenge coins to present to foreign guests, diplomats and members of the military.

A number of the coins are available for sale through the White House Gift Office.
