He was speaking to representatives from the Party Central Committee's Commission for Communication and Education as part of a review of the body's performance last year and a look ahead to their tasks for 2013.
The Party leader lauded the commission for achieving resolutions laid out during the 11th National Party Congress.
He specifically praised the majority of communication and education departments throughout the country for spreading word of the Party's resolutions through various innovative means, allowing people at grassroots level to contribute to the State's policy-making from the beginning.
However, he also noted that in some cases the work was not fulfilled satisfactorily as officials did not study the public well enough and were unsuccessful in clearly spreading important messages.
General Secretary Trong also reprimanded the sector for remaining slow in responding to incorrect information released about political, economic and social issues.
The leader asked the body to thoroughly grasp the national and international socio-economic and political situation in order to accomplish their aims this year, particularly when collecting the vital ideas and comments of citizens in regards to amendments to the 1992 Constitution.
He declared that the country has never before had such a big force working in the sector, which now includes over 800 media organisations and 17,000 journalists.
He called for workers to renew their working methods in order to spread information through diverse and modern information channels.
As well as taking advantage of media, the Party leader said the sector should pay more attention to educating the public through word of mouth.
