Foreign ministers from the Group of Seven nations are planning to hold talks later this month in New York on the sidelines of the U.N. General Assembly to reaffirm their unity amid Russia's invasion of Ukraine, diplomatic sources said Wednesday.

The first foreign ministerial meeting of "Partners in the Blue Pacific," a U.S.-led initiative aimed at stepping up engagement with Pacific island countries, is also under arrangement there, the sources said.

The top diplomats of "the Quad" group, consisting of Japan, the United States, Australia and India, are expected to gather as well during the period of the U.N. main policymaking organ's annual session that began Tuesday and is scheduled to last about two weeks, they added.
