Revised regulations on internal management, discipline and formation regulation of the People's Liberation Army (PLA) are issued Thursday to further advance the army's development and modernization.

Chinese President Hu Jintao, also Chairman of China's Central Military Commission, recently signed an order to promulgate and enforce the three regulations.

Unlike the previous version, the revised regulation on internal management adopted provisions on psychological counselling to armymen and provisions on their use of mobile phones and the Internet.

It also modified a wide range of provisions covering oath, dress and bearings, as well as confidentiality rules, security systems and financial management.

The three revised regulations are to come into force from June 15 this year.
