 The construction industry has been negatively affected by the move of state apparatus and civil servants to Naypyidaw, new regulations introduced in August 2009 requiring builders to provide at least 12 parking spaces in every new high-rise building, and the general poor business climate.As of January 2010, the number of new high-rise building starts approved in 2009–2010 was only 334, compared to 582 in 2008–2009.Tourism represents a major source of foreign currency for the city although by south-east Asian standards the number of foreign visitors to Yangon has always been quite low—about 250,000 before the Saffron Revolution in September 2007.
