Hien made the remarks in a recent interview with Xinhua and other Chinese media on the upcoming visit to Vietnam by General Secretary of the Central Committee of the Communist Party of China (CPC) and Chinese President Xi Jinping.
Xi will pay a state visit to Vietnam from Nov. 5 to 6 at the invitation of the CPV General Secretary Nguyen Phu Trong and Vietnamese President Truong Tan Sang.
"Vietnam and China are countries with geographical proximity, sharing the common goal of building socialism. The two countries have many things in common such as their revolutionary careers being led by communist parties," Hien told Xinhua.
"As a result, official visits by the two parties' leaders, which are of great importance, are expected to bring about comprehensive and strategic orientations to the relations of the two parties and two countries," the official added.
Since 2003, following agreements reached between the CPV and CPC Politburos, workshops on theory have been held 11 times with various themes.
These topics include China's experience in reform and opening up, Vietnam's experience in renovation, enhancing governance capacity of the parties, experience in developing market economy in each country, response to the global financial and monetary crisis, dealing with Three Rural Issues, and building culture in each country, among others, said Hien.
