Prime Minister Shinzo Abe said on Friday that he and U.S. President Donald Trump agreed to meet in the United States next month, following Washington's announcement that Trump is ready to meet North Korean leader Kim Jong Un for the first time ever.

During a 30-minute teleconference with Trump, Abe said they agreed to hold the summit in April to discuss North Korea and the long-unresolved issue of Japanese citizens abducted by North Korean agents in the 1970s and '80s — one of the top priorities of the Abe administration.

Tokyo welcomed Pyongyang's stated commitment to denuclearization as a victory for the two allies' "maximum pressure" campaign and stressed that they will, as always, remain "100 percent together."
