The Greenland deal announced in September 2026 was expected to be formally signed at which multilateral gathering the following week?

Explanation: The Greenland security deal between the United States, Denmark and Greenland was expected to be formally signed by all three governments at the United Nations General Assembly session the following week, according to statements from the Danish prime minister's office. Using the UN General Assembly as a venue for signing such agreements is a common diplomatic practice, given the concentrated presence of numerous heads of state and government in New York during the annual High-Level Week.
