China will help promote cooperation among Eurasian countries by launching the fourth China-Eurasia Expo in September, the China-Eurasia Expo Secretariat said on Thursday at a meeting in Beijing .

The Expo is key to deepening friendship and "neighborship" among Asian and European countries, said Anvar Nasyrov, deputy secretary-general of the Shanghai Cooperation Organization.

Deepening cooperation in Asian and European countries and regions not only meets each other's needs, but also the need for world development, said Li Jingyuan, secretary-general, China-Eurasia Expo Secretariat.

With joint efforts from all sectors of society, the expo has been held every year since 2011.
