Bulgaria started its accession negotiations with the WTO predecessor GATT. However, the negotiations were suspended at some point and had to be reopened with the new organization after it was formed in the beginning of 1995. Bulgaria is the last of the former Soviet-bloc states in Europe to join WTO. The WTO membership is one of the preconditions for the Bulgarian membership in CEFTA- an economic organization comprised at present of Poland, Hungary, the Czech Republic, Slovakia and Slovenia.
