As of 2019, which country has the least number of visitors each year?

Tuvalu (formerly known as the Ellice Islands), is a country in Polynesia, located in the Pacific Ocean, situated in Oceania and about midway between Hawaii and Australia. The island country lies east-northeast of the Santa Cruz Islands (which belong to the Solomon Islands), southeast of Nauru, south of Kiribati, west of Tokelau, northwest of Samoa and Wallis and Futuna, and north of Fiji.

Due to the country's remoteness, tourism is not significant. Visitors totalled 1,684 in 2010: 65% were on business, development officials or technical consultants, 20% were tourists (360 people), and 11% were expatriates returning to visit family. In 2016, the number of visitors had increased to 2,000.

The main island of Funafuti is the focus of travellers, since the only airport in Tuvalu is the Funafuti International Airport and Funafuti is the only island that has hotel facilities. However, there are no tour guides, tour operators or organised activities and no cruise ships visit. Ecotourism is a motivation of travellers to Tuvalu. The Funafuti Conservation Area consists of 12.74 square miles (33.00 square kilometres) of ocean, reef, lagoon, channel and six uninhabited islets.
