There are territorial issues all over the world.
Japan also has territorial issues, such as the Northern Territories illegally occupied by Russia in the confusion that followed World War II, and the Takeshima issue, where South Korean troops took over the island on their own just before Japan signed a peace treaty.
The Philippines also has the problem of the Nansha Islands, which have been effectively controlled by an intransigent China in recent years.
It is very difficult to resolve these territorial disputes through discussions, and although they are sometimes resolved peacefully by buying, selling, or exchanging territory, most have been done through the use of force to seize territory (the winner takes the territory).
One such territorial issue that is being talked about as having been resolved peacefully through talks is the territorial dispute over Hans Island, a small island on the border of Canada and Denmar's Greenland.
The map shows a really small island, only 1.3 km2 in size. However, there have been territorial disputes because the island is on the sea route between Europe and North America due to the melting of the surrounding ice due to global warming, and also because the development of fisheries and marine resources is being considered.
The conflict between Canada and Denmark was quite peaceful, with troops from both countries occasionally landing, raising flags, and leaving behind boxes of their own whisky, in what was known as the "Whisky Wars.
This "war" had been going on, but on June 14, the two countries agreed to divide and own the island, so the "Whiskey War" is said to have come to an end.
On that day, the Canadian Foreign Minister handed a Canadian whisky and the Danish Foreign Minister handed his counterpart a Danish distilled spirit, schnapps.
Cheers to both countries!
