Lots of important people from different countries came to Tonga for a big meeting about the Pacific Islands.
Countries like China and Australia want to be friends with the islands and help them, but they also want to be the most important friend.
There's a special fund to help the islands fight climate change, which is really important because the ocean is getting warmer.
Even though the islands are small, they're really important because the ocean around them is huge and affects the whole world.
