Yes, Cofty, Hong Kong was really a commerical agreement, just a lease for 99 years, a land with very considerable Chinese population.
Fact: the Falkland Islanders are British, see themselves as British, want to be British, want the British there for protection (read the above for why) and most emphatically want their wishes to be respected. They use British currency as well as the Falkland pound, live under English common law,
Britain respects their wishes, and firmly believes in and supports those who believe in self-determination.
Fact: David Cameron no doubt found it inappropriate to talk to Cristina Fernandez about the Falkland Islands when she herself, on June 15th, refused to talk with the Falkland Islanders themselves; she also refused to accept from them the letter they attempted to hand her in person at the United Nations.
The Falkland Islands Government website is illuminating. If anyone is in any doubt what the islanders want, just visit it and explore.

You'll see that members of the Falkland Islands Legislative Assembly addressed a Committee of the United Nations.
Member of the Legislative Assembly, Gavin Short, spokesperson for the Legislative Aseembly, said
“We are incredibly disappointed that the President of Argentina refused to accept an invitation from the Falklands Island Government to sit down and discuss the Falkland Islands.
“This is representative of the Argentine Government’s policy towards the Falkland Islands people – to ignore us, to deny our human rights, and to deny our rights as a people to determine their own future.”
