Japan is arranging to include in a statement for the upcoming Group of Seven summit in Hiroshima a mention of the importance of directly expressing concerns to China, a diplomatic source said Thursday.

The G-7 leaders, like in previous annual summits, are also expected to highlight the necessity of peace and stability over Taiwan, a self-ruled island Beijing views as its own territory, while opposing any "unilateral attempts to change the status quo by force or coercion," the source said. Japan is the group's chair in 2023.

As for Russia, which launched its ongoing invasion of Ukraine in February 2022, the G-7 leaders are likely to show their commitment to maintaining strict sanctions on Moscow as well as addressing schemes to evade or circumvent such measures through third-party countries, the source added.

The three-day G-7 summit is scheduled to kick off on Friday, with the global security situation deteriorating amid China's growing military assertiveness in the Asia-Pacific region and Russia's threats to use nuclear weapons against its neighbor.

Japanese Prime Minister Fumio Kishida has reiterated that it is significant to continue communicating well with Beijing to avoid any contingency in areas including the Taiwan Strait and the East China Sea, with Sino-U.S. tensions intensifying.

China regards Taiwan as a renegade province to be reunified with the mainland, by force if necessary.

At the summit in the western Japan city that was devastated by a U.S. atomic bomb in 1945, the G-7 is expected to refer to the need for early ratification of the Comprehensive Nuclear Test Ban Treaty and the immediate start of talks on the Fissile Material Cut-off Treaty in either the leaders' communique or a separate statement focusing on nuclear disarmament.

The second treaty would prohibit the production of materials for use in nuclear weapons. China and some other nations are believed to be increasing their production of military-usable plutonium.

The G-7 communique, meanwhile, is also likely to vow efforts toward promoting trustworthy artificial intelligence as issues stemming from generative AI such as ChatGPT have captured public attention recently, the source said.

It will also touch on Japan's cooperation with the International Atomic Energy Agency on its planned discharge of treated radioactive water into the sea from the disaster-hit Fukushima nuclear power plant, amid fears about potential negative effects.

In a separate document focusing on Ukraine, the G-7 leaders may also pledge to take every measure to bring permanent peace to the Eastern European country.
