Pakistan and India should clearly commit themselves to the nonproliferation of nuclear technologies to third countries and sign the Comprehensive Nuclear Test Ban Treaty, Foreign Minister Masahiko Komura told ambassadors of the two countries Tuesday in separate meetings, according to Foreign Ministry officials.

Komura told Pakistani Ambassador to Japan Touqir Hussain and Indian Ambassador Siddharth Singh that nuclear tests conducted by Pakistan and India in May hampered peace and stability both globally and regionally, the officials said.

Hussain told Komura he hopes Japan will ease economic sanctions against Pakistan, they said. Japan froze grants and new yen loans to Pakistan and India after they conducted the tests.
