Trade between the Greater Bay Area and BRICS economies is gaining momentum, as growing demand for technology, consumer goods and agricultural products creates new opportunities for businesses across the region.   Shenzhen is at the heart of the expansion. Its trade with BRICS members reached 246 billion yuan (US$34.6 billion) in the first eight months of the year, up 11.5 percent from last year.   The city’s technology companies are finding growing markets overseas. Rock Times Technology has entered Brazil with AI-powered cleaning devices, while LED display maker Absen saw exports to South Africa rise nearly 10 percent, driven by demand from transport hubs, commercial venues and sporting facilities.   Trade is also flowing in the other direction. Streamlined customs procedures have helped Shenzhen bring in more than 70,000 tonnes of Brazilian meat this year.   Hong Kong is adding to the momentum, with exports to the UAE up 53.8 percent and imports from India more than doubling in the first half.
