At the onset of China's opening-up and reform, export-oriented manufacturing was a key driver of the country's economy.

Despite a clear shift to more services and innovation-based development in recent times, an upgrade to the industrial chain is seemingly retaining the robust role manufacturing plays, especially in the southern province of Guangdong.

The province has issued a series of policies to expand and upgrade the region's manufacturing capabilities as part of the nation's Five-Year Plan. Hopes are that by 2025, the added value of the manufacturing industry in Guangdong will remain above 30 percent of GDP. Meanwhile, designated advanced manufacturing industries and high-tech manufacturing will surpass 60 and 35 percent, respectively.

Economic planners also have their sights set on specific emerging industrial chains and clusters, including green petrochemicals, intelligent home appliances, the automobile industry, biomedicine and health, and modern agriculture and food industries. The plan also includes intelligent robotics, blockchain development and a focus on environmental protection.

These newly drafted plans may be aimed at companies just entering their specific industry or market. But what does it mean for well-established enterprises that have been at the core of China's manufacturing base?

For Dongguan Vision Tool & Mould, one of the country's top producers of vehicle moulds, China's decades of experience and industrial development have allowed companies like theirs to prosper.

"Looking at the whole manufacturing chain, our cost advantages are quite clear. In terms of overall dependence, China's mould output accounts for 25 percent of global public rail exports, with only 5 percent of imported moulds coming to China. So, we basically transport domestically produced moulds to the entire world. And in terms of technology, we meet those standards," said Liu Xialong, the company's general manager.

Though a rather niche industry and not capturing the wide range of manufacturing in the country, Liu sees the industrial chain upgrades as more of an opportunity than a burden for existing companies.

According to him, the country's mould enterprises have shown the advantages of further speeding up the optimization and upgrading of products, more sophisticated equipment capacity has been deployed, industrial collaboration has transformed, and cooperation with downstream industries and further enhancement of international competitiveness have taken place.
