Reportedly, U.S. President Donald Trump has proposed for the U.S. to buy Greenland from Denmark, an idea that has been rejected by Greenland and Denmark, with one politician quoting it as this is not the 19th century.
Are there any more recent examples or has this idea gone out of fashion in the past century? When was the last time that a sovereign state acquired land from another sovereign state through purchase, including a transfer of sovereignty? Is this list on Wikipedia complete? I mean land purchases that include travel of sovereignty. Otherwise any state-owned real estate purchase would count. –
