Greenland's leaders are not happy about visits from US officials. They think the visits are aggressive. The US wants to visit Greenland to learn about its culture and people. But Greenland's leaders say the US did not ask them first.

Greenland is a big island. It is between the Arctic and Atlantic Oceans. Denmark controls it, but Greenland makes its own local decisions. The US has a military base there. The US is interested in Greenland's minerals too.

President Trump wants Greenland to be part of the US. He talked about this with a Nato leader. Greenland's leaders do not like this idea. They want to be independent from Denmark, but they do not want to join the US.
