"Cuban ruler Raúl Castro, breaking his own promise to move ahead with economic reforms 'without haste but without pause,' has stopped issuing government licenses for some of the more lucrative private businesses on the island such as private restaurants and B&Bs.Other frozen occupations include services for home repairs and electronic equipment, developers of applications for cell phones and web pages, music teachers, education tutors and even blacksmiths."

"Havana’s new restrictions may signal that Castro fears losing control of that future, experts said. But they warned that the move will have a negative impact not only on private entrepreneurs but also on the overall economy and its ability to attract foreign investments."
