Australian Prime Minister Anthony Albanese said that both Australia and China have benefited from regional development and stability. He said that trade in goods and services has nearly doubled since the China-Australia Free Trade Agreement came into force in 2015, making more high-quality Australian products available to consumers in China and providing key inputs to Chinese businesses.

The convening of the 6th CIIE will help the international community promote a global economic recovery and world trade development more innovatively and effectively, said Marrero.

China is Kazakhstan's largest trading partner, and bilateral cooperation has achieved a series of results, said Kazakh Prime Minister Alikhan Smailov, adding that more than 30 Kazakh enterprises take part in the 6th CIIE.

Kazakhstan will continue to use the platform to bring more of its high-quality products to the vast Chinese market, said the Kazakh prime minister.

The next "30 golden years" of Kazakhstan-China relations will witness substantial development opportunities, with economic and trade cooperation playing an important role, the Kazakh prime minister added.

The sixth CIIE is a "good opportunity to further consolidate and deepen Serbia-China relations," said Serbian Prime Minister Ana Brnabic.

She said that Serbia is one of the first countries to recognize the importance of the expo, adding that the country has attracted many Chinese investors. From 2018 to 2022, trade between the two countries increased significantly, with Serbian exports to China up 12.7 percent.

The CIIE shows China's commitment to balancing trade relations with countries worldwide, said Rebeca Grynspan, secretary-general of the United Nations Conference on Trade and Development.
