On April 18, 2023, G7 Foreign Ministers met in Karuizawa, Japan, and issued Communique (PDF) containing the following paragraph relating to the rule of law among nations:
“The prohibition of threats or the use of force against the territorial integrity or political independence of any state, in accordance with the provisions of the UN Charter, constitutes the cornerstone of the post-war international system. Yet, territorial ambition is again driving some states to return to rule by force, so we have redoubled our efforts to uphold peace guided by the rule of law. The prohibition on the acquisition of territory resulting from the threat or use of force, reaffirmed in the Friendly Relations Declaration of 1970, should be observed in good faith. We strongly oppose any unilateral attempts to change the peacefully established status of territories by force or coercion anywhere in the world. In this regard, sending regular or irregular forces to unilaterally annex a territory is prohibited..”
