The American vice president went to Greenland, a big island near the North Pole, and talked to people there.
He said Greenland should be friends with America to stay safe from other countries, but some people didn't like that idea.
Greenland wants to be its own country and make its own choices, not just listen to America.
It's like when you want to choose your own toys, not have someone else choose for you, it's important to make your own choices.
