The chairman of Polytechnic University (PolyU)'s governing council on Thursday said Hong Kong must make use of its super-connector role under One Country, Two Systems to support the nation's diplomatic efforts.

At a seminar focusing on China's diplomacy in the new era, Lam Tai-fai said Western countries such as the United States are creating problems through unfair practices like sanctions and protectionism.

On the other hand, Lam added, Beijing continued to promote peace and cooperation through building friendships with countries. He said one of PolyU's missions is to nurture patriotic students with a global perspective.

Also at the seminar was Huo Yuzhen, former Chinese ambassador to the Czech Republic and Romania.

The veteran diplomat was involved in a Foreign Ministry initiative aimed at fostering cooperation between China and Central and Eastern European nations, such as Poland, Greece and Serbia.

She described the initiative, which began in 2012, as a success, pointing to achievements in many areas which benefitted the people of both sides.

Looking ahead, Huo suggested focusing on new areas of cooperation, such as green energy, advanced technology, and artificial intelligence.

At the same event, former Chinese ambassador to Georgia and Tajikistan Yue Bin spoke about the development of Sino-Russian relations.

Yue described how the bond between the two neighbours has grown stronger over time, evolving into a comprehensive strategic partnership building on mutual trust.
