In September 2021, the Group's wholly-owned subsidiary, Asian Green Tech Pte. Ltd ("AGT"), entered into a joint venture agreement ("JVA") with X Diamond Capital Pte. Ltd. ("XDC") to establish a joint venture and AET was incorporated in Singapore to carry out the business of manufacturing and distribution of lab-grown diamonds. Under the JVA, AGT shall operate and manage AET while XDC shall provide technical support to AET.

Diamonds are more widely known to be used in jewellery but diamonds are also commonly used for industrial applications in medical equipment, aerospace, semiconductors, among others.

As lab-grown diamonds are created without the need for mining, they are a more sustainable production of diamonds and there are also opportunities to integrate renewable energy in such manufacturing activities, hence it is aligned with the Group's environmental and sustainability business model.

Ms. Samantha Hua, Deputy Chief Executive Officer and Executive Director of Metech, said: "China is currently the second-biggestconsumer of diamonds in the world. With the price-valuerelationship and sustainability features of lab-growndiamonds, we believe that the lab-growndiamond market in China has strong potential ahead as consumers make more informed and conscious decisions on jewellery purchases.

Guangzhou Diamond Exchange is an internationally-recognised diamond exchange and we are pleased to collaborate together with the aim to drive deeper collaborations across the industry and create new value propositions within the lab-grown diamond market in China."
