As Vietnam is tightening control of illegal software, local administrations and enterprises are seeking cheap alternatives and open source software has become the top choice. In 2004, the Vietnamese government kick-started a national open source software development programme for 2004-2008. This programme, however, has not had any impact on the development of open source software in Vietnam, as it remains on paper.
However, the situation has changed. Recently the government has asked state agencies to use authentic software products. As those products are expensive, state agencies are seeking open source software.
