Colombia said on Friday that it had completed talks with the United States over the use of Colombian military bases.
The two countries reaffirmed their joint commitment to fight drug-trafficking and terrorism in the region, the Foreign Ministry said in a statement.
The text of an agreement has been reviewed by government agencies before getting a final approval, it added.
Under the agreement, Washington could gain access to at least seven Colombian military bases by the year 2019, and in return, Washington would offer Bogota some 5 billion U.S. dollars in aid.
Though the United States and Colombia have said the plan was designed to strengthen Colombia's anti-drug and anti-rebel efforts, many South American countries have voiced their concerns.
