Cuba has yet to attract new foreign investors despite launching two major initiatives in the past year, a sign of the lingering caution over doing business with the communist government and its own hesitancy to follow through on free-market-style reforms. Cuba last November opened a China-style special development zone, including a new container terminal at Mariel Bay. It also passed a new foreign investment law in March, saying it needed more than $2 billion a year in foreign direct investment to spur growth.
