Top officials from seven of the world’s most economically powerful countries vowed to work together on North Korea denuclearization in a joint statement issued on Tuesday.

The G7 countries — which include the United States, the U.K., Canada, France, Germany, Italy and Japan — specifically said they will work on the “complete, verifiable and irreversible denuclearization and dismantlement” of all North Korean nuclear and ballistic missiles. Among foreign policy experts, this ultimate goal is often referred to using the acronym CVID.
