The economic disadvantages of being landlocked can be alleviated or aggravated depending on degree of development, surrounding trade routes and freedom of trade, language barriers, and other considerations. Some landlocked countries are quite affluent, such as Andorra, Austria, Liechtenstein, Luxembourg, San Marino, Switzerland, and Vatican City, all of which, excluding Luxembourg, a founding member of NATO, frequently employ neutrality in global political issues. The majority, however, are classified as Landlocked Developing Countries (LLDCs). Nine of the twelve countries with the lowest Human Development Indices (HDI) are landlocked. International initiatives are aimed at reducing inequalities resulting from issues such as these, such as the United Nations Sustainable Development Goal 10 which aims to reduce inequality substantially by 2030.
