 The Public Procurement and Concessions Commission (PPCC) was established in 2005 to "regulate all forms of Public Procurement and Concessions and provide for institutional structures for public procurement and concessions".The PPCC operates an online Vendors' Register.Procurement is decentralised, but the Ministry of Finance is required "to take part in the negotiations and signing of contracts over US$250,000" and such contracts must "be attested to by the Ministry of Justice".
