Intending to make Palau less dependent upon United States aid, Remengesau has promoted the expansion and growth of tourism in Palau with the slogan "Preserve the Best and Improve the Rest". The "best" refers to Palau's especially bountiful and diverse marine water resources surrounding the islands, and, as a venue of underwater attractions, its reputation among the very top in the world. In foreign affairs, Remengesau has actively advanced Palau's presence in the United Nations, elevating Palau to leadership among the international community through such environmental initiatives as the Micronesian Challenge. He is also a leader among South Pacific nations in advocating awareness of global warming and its effects in the South Pacific Region.
