Revenue from Egypt's Suez Canal rose 9 per cent year-on-year to US$413.5 million in March and 6.4 per cent from a month earlier, a state website showed on Monday. Revenue in March 2010 was $379.4 million. Revenue in February 2011 was $388.7 million. The waterway is a vital source of foreign currency in Egypt, along with tourism, oil and gas exports and remittances from Egyptians living abroad.
