Central and provincial governments have investigated 3,600 enterprises. More than 1,100 companies have faced penalties for using pirated software, Liu told a conference on software copyright issues.

Vice Premier Wu Yi, also leader of a national working group for intellectual property protection, said in a congratulatory letter to the conference that software industry was a "basic and strategic sector" of the national economic development.

Wu said the use of copyrighted software to create a healthy and standard market environment is very important to develop the software industry.

The meeting, attended by 300 delegates from various software companies, also heard that China was working to promote the use of legitimate software by official organizations.
