TEHRAN, Iran (AP) — Iran's vice president told The Associated Press on Sunday his country is preparing for a "tsunami" of foreign tourists as Iran and world powers are set to begin implementing a landmark nuclear deal that will lift sanctions in return for curbs on Iran's nuclear program. Masoud Soltanifar, who is also Iran's Cultural Heritage, Handicrafts and Tourism Organization chief, said President Hassan Rouhani's moderate policies and the easing of visa rules are opening the door for the return of foreign tourists to Iran. A country rich in historical and cultural treasures largely unseen by Western eyes, Iran will unveil an investment package of 1,300 projects in the coming days to attract foreign investment and boost the badly-hit tourism industry. Soltanifar, a member of Rouhani's Cabinet, said officials are trying to remove obstacles for tourists and issue visas on arrival at the airport in Tehran for nationals of 190 countries. Last week, an Iranian passenger plane safely landed after part of an engine fell off during a flight with 426 passengers and crew members aboard. Iran's constitutional watchdog, the Guardian Council, ratified into law this week a parliamentary bill implementing the landmark nuclear deal with world powers.
