The leaders of Japan and the United States agreed in telephone talks Monday on the need to heap more pressure on nuclear-armed North Korea as it heads down what the White House termed a "dangerous path."

The talks between Prime Minister Shinzo Abe and U.S. President Donald Trump, also saw Washington reaffirm its commitment to "defend and respond to any threat or action taken by North Korea."

To discuss options for tackling the North's growing threat, the two leaders confirmed that they will hold trilateral talks with South Korean President Moon Jae-in on the sidelines of the Group of 20 summit, which begins Friday in Germany, Kyodo News quoted Deputy Chief Cabinet Secretary Koichi Hagiuda as saying.
