BEIJING, June 1 (Xinhua) -- A trade fair in Beijing has shown that China is making a steady steering on growth in knowledge and technology-intensive services.

BEIJING, May 23 (Xinhua) -- Since the beginning of 2018, the United States, carrying the flag of "America First," has been enthusiastic about wielding the tariff stick against its trade partners including Mexico, Canada, the European Union (EU), Japan and China.

Huang required staff of the sector to focus on developing philosophy and social sciences with Chinese characteristics, base their studies on Chinese practice, and strengthen forward-looking research on issues that concern the whole landscape and have strategic significance.

Under the MoU, which is valid for five years, both sides have agreed to strengthen STI cooperation in areas including advanced materials, information and communications technology (ICT), life sciences, food and agriculture.
