The Obama administration has announced sweeping new rules that will significantly ease sanctions on Cuba while opening up the island to expanded U.S. travel, trade and financial activities. The new regulations will allow Americans to travel to Cuba for any of a dozen specific reasons, including family visits, education and religion, without first obtaining a special license from the U.S. government. But general tourism will still be banned. While the overall trade embargo remains, the new rules will make it easier for U.S. companies to export mobile phone devices and software as well as to provide Internet services in Cuba.
