Greenland is an autonomous constituent country within the Kingdom of Denmark. It has its own parliament, called the Inatsisartut, which is made up of 31 members. The Parliament is responsible for most of the laws and regulations governing Greenland. The Prime Minister heads the government in Greenland and is responsible for implementing laws and regulations passed by the Parliament. Greenland also has an independent judicial system consisting of a Supreme Court, a High Court, and several lower courts. All decisions made by the courts are subject to review by the Supreme Court if necessary. The autonomy of Greenland means that it has its own foreign policy, though Danish diplomats often represent Greenland in international relations. In recent years, Greenland has been increasingly focused on developing its economy and expanding its tourism industry in order to become more self-sufficient and less reliant on subsidies from Denmark.
