Leaders of the Group of Seven industrialized nations will hold a meeting in Brussels alongside an emergency summit of the NATO to discuss measures against Russia for its continued aggression in Ukraine.

Japan is the only country in the G-7 - comprising also Britain, Canada, France, Germany, Italy and the United States - which is not a member of NATO. Japanese Prime Minister Fumio Kishida is expected to travel to the Belgian capital.

G-7 summit will be led by U.S. President Joe Biden, who is aiming to demonstrate unity not only within the framework of NATO but also the G-7 to keep up pressure on Russia.

The G-7 leaders are expected to discuss additional sanctions and other measures against Russia and Belarus, as well as exchange views on how to stabilize the energy market, including the soaring price of crude oil.
