The Communist Party of China (CPC) Central Committee Monday called on it members to strengthen learning Marxist theories and various fields of knowledge as required by the country's modernization drive.

A circular issued by the General Office of the CPC Central Committee said, "Be it a country, a nation or a party, if it does not strengthen study or enhance the learning ability, it will certainly be left behind by the time."

It said as China has entered a new development stage, new problems will constantly emerge and "there are many things that we are not familiar with, or do not understand."

It called on CPC members to deeply learn the Marxist theories, the Party's guideline principles, policies, history, and the country's laws and regulations, as well as various kinds of knowledge that would be useful in the modernization drive.

It said efforts should be made to study the Scientific Outlook on Development, the core of policies of the leadership which has been enshrined in the Party's constitution and stresses a comprehensive, balanced and sustainable development that is people-oriented.
