Semiconductor sales by Chinese manufacturers are said to have reached ¥653.2bn in 2018 – that's about $97.3bn, or around 20 per cent of global semiconductor revenue for the year ($476.7bn).

The number was claimed by Ren Aiguang, head of the integrated circuits office at China's Ministry of Industry and Information Technology, at a meeting held in the manufacturing hub of Shenzhen, and reported in the state-owned Xinhua News.
