"Ethiopia is in the third phase of the WTO accession process, where the terms of accession will be drafted."
Only the following 14 countries are not WTO members: Aruba, Eritrea, Kiribati, Kosovo, Marshall Islands, Micronesia, Monaco, Nauru, North Korea, Palau, the Palestinian Territories, San Marino, Sint Maarten, and Tuvalu.
Hope this helps!
