As a key node on the ancient Maritime Silk Road and an essential hub for maritime trade today, Malacca hopes to work more closely with Jiangxi and other Chinese provinces on green development and future cooperation, he said.

Yin Hong, secretary of the CPC Jiangxi Provincial Committee, noted that this year marks the 20th anniversary of China's guiding ecological principle that "lucid waters and lush mountains are invaluable assets", known as the "two mountains" concept.

He said Jiangxi is advancing a range of initiatives, from waste-to-energy projects to halal-food industrial parks and low-carbon industrial zones.

Yin also called on all sides to move forward together, seize new opportunities in green investment and trade, and help build a cleaner and more beautiful world.

Jiangxi has 155 million mu of forest, ranking second nationwide in forest coverage. As of October, 44 companies in the province had participated in China's carbon market, purchasing 5.7 million tons of carbon credits valued at about 370 million yuan, and selling 15 million tons worth roughly 1 billion yuan ($141 million).

More than 2,000 exhibitors from over 60 countries and regions are taking part in this year's expo.
