Prime Minister Fumio Kishida is making arrangements to attend a NATO summit scheduled for July, government sources said Wednesday, as Japan has deepened ties with the trans-Atlantic alliance amid global security concerns.

On the sidelines of the summit in Lithuania, Kishida is expected to hold bilateral talks with NATO Secretary General Jens Stoltenberg to discuss the organization's plan to open a liaison office in Tokyo, the sources said.

Kishida and Stoltenberg are also likely to map out a new Japan-NATO security cooperation document, called the Individually Tailored Partnership Program, to work closely with each other in areas such as space and disinformation response, the sources said.
