+NEW QUESTION+
Ok, since it is now my turn:
What do the following countries have in common? Jamaica, Moldova, Tanzania, India, Lesotho, Mauritania, Dominica, Sri Lanka, Uganda, Zambia, Malawi, Bhutan, Malta, Liechtenstein, Armenia, South Korea, Marshall Islands, Vatican City.
To be clear for jmo's benefit, all the countries share one thing, which is not (to my knowledge, and I've checked) shared by any country not on that list.
What is the answer?
