The report says that Chinese officials are evaluating whether the target for economic growth this year – touted to be ‘around 6% growth’, should be softened as part of a broader review of how the government’s plans will be impacted by the new coronavirus outbreak.

I reckon the date to watch for any official changes to China’s economic target and plans will come via the National People’s Congress, which is to begin on 5 March.
But given the situation surround the coronavirus outbreak, we’ll have to see if the session will progress according to schedule or not – should things not calm down by then.
