Countries that are landlocked all sides by one country?

Question

Can you name some countries that are landlocked on all sides by just one country. if they have an ocean/sea on one side and surrounded on three sides by a country, that doesn't count - eg Monaco is surrounded on three sides by France.

Answer 2

Lesotho is surrounded by south africa and is the only other one besides the ones you named
