Hundreds of foreign diplomats and representatives of overseas companies, chambers and organizations sat down Wednesday to hear more about the 19th National Congress of the Communist Party of China.

Guo Yezhou, vice-minister of the International Department of the CPC Central Committee, briefed them on the meanings of some key words such as new thought, new era and new achievement.

The 19th National congress was especially important as it was held while the country undergoes a decisive period of constructing a moderately prosperous society in an all-round way and the socialism with Chinese characteristics enters a new era, Guo said.

He said "Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era" has been included into the Party's Constitution and it is a political declaration and a guide of action for the Party to start new journey in the new era.

The envoys and representatives enquired about China's diplomatic policies, such as in Africa, and the opening-up policy.

China remained committed to the principle of treating countries, big or small, equal in relationship, Guo said, and the country will push forward a new type of ties and will discuss and collaborate with other nations in building a community of shared destiny for mankind.

He said Xi remarked in a meeting with Tsinghua University advisors recently that the country will firmly stick to the basic national policy of opening-up, and will take more measures to boost opening-up.

The vice-minister said that the Party would like to invite leaders of foreign parties to take part in another event.
