Lawmakers gave final approval Tuesday to a $55 million loan to improve the docks at Moín. There were no negative votes.
The work will be under the Junta Administrativa de la Vertiente Atlántica, which runs the ports on the Caribbean.
The Moín port is used only for cargo, petroleum and chemicals, unlike the docks at Limón where cruise ships frequently dock.
The government has contracted with a Dutch firm to build a $1 billion container handling facility, and workers at the public docks staged protests and strikes until the government agreed to improve those docks, too.
APM Terminals will be building its container facility at Moín, too.
