Twitter is blocked in China, but a few Chinese government institutions or officers have set up their official accounts on Twitter. For example, @loveJiangSu is a verified official account of the government of Jiangsu Province.
Then how about the business? I tried to look for the official verified Twitter accounts of the largest Chinese companies (by annual revenue according to Fortune 500) and had the following discoveries:
State Grid Corporation of China (No. 3 in China & No. 5 global): no official account.
Industrial and Commercial Bank of China (No. 5 in China & No. 26 global): no official account.
Among those who have twitter accounts, none attracted larger followers compared to the size of the corporations. Twitter has not been considered a platform in these companies’ branding and PR (if any) strategy.
Huawei is ranked No. 16 in 2018 by revenue, and it does have an active official Twitter account: @huawei, which was registered in December 2009 and got 1.6 million followers.
According to another approach of ranking – calculating the largest Chinese company. The most valuable companies in China are Tencent and Alibaba.
Alibaba has an active official Twitter account: @AlibabaGroup, which attracted 153K followers since its opening in July 2014.
The second-largest Chinese company (by capital value) is Tencent, which also has an active Twitter account @tencentglobal, which attracted about 9936 followers.
