Following a meeting with diplomats from Spain and Italy in Panama City, Martinelli also said that the governments of Panama, Spain and Italy are ready to work together to make sure the massive infrastructure project is completed.

The Spanish ambassador to Panama, Jesus Silva, said Sacyr still wants to see the expansion completed.

A building consortium behind the project - which includes Sacyr (>> Sacyr SA), Italy's Salini Impregilo (>> Impregilo SpA), Belgium's Jan De Nul and Panama's Constructora Urbana - said earlier this week that $1.6 billion (974.4 million pounds) in cost overruns on the $3.2 billion plan to build a third set of locks for the canal should be met by Panama.
