Aside from wholesale and retail trade, transportation, and communications, the services sector consists almost entirely of tourism. Developed in the 1960s, tourism declined greatly during the later 1970s and the 1980s under the military government. Recovery began in the 1990s, but growth has been constrained by the lack of suitable hotels and other infrastructure, despite a boom in construction of small and medium-sized hotels and restaurants, and by the impact of drought, the 1998–2000 war with Eritrea, and the specter of terrorism. In 2002 more than 156,000 tourists entered the country, many of them Ethiopians visiting from abroad, spending more than US$77 million. In 2008, the number of tourists entering the country had increased to 330,000.
