Austria and Switzerland.

Explanation:

A landlocked country is one that is a sovereign state and 49 countries in the world are landlocked. They are surrounded by the land on all sided and thus depends on the other neighboring country if resources and political and economic significance. An example of Liechtenstein is double landlocked in central Europe and is surrounded by Austria and the switzerland. Austria has a land cover of 83,871 km square with a population of 8,823,054 people and Switzerland has an area of 41,284 km square with a population of 8,401,120 persons. Both have 5-8 countries that surround their borders.
