First, it's oversupply and not overcapacity. Overcapacity in this context is a political slogan because US cannot pin dumping on China. Dumping is an unacceptable trade practice but oversupply is just natural business cycle. White House hijacked and twisted the term overcapacity to paint China evil because China is clearly not dumping. Most reputable news outlets are very careful when using the word overcapacity in this context to avoid being seen as pushing a propaganda, at least for the time being. Overcapacity used to be a good thing because when a company is running at overcapacity it means demand is so strong the company is producing beyond its designed capacity. A venue is overcapacity when there are too many patrons. It's very 1984-ish that overcapacity is being used as an accusation by state media and the irony is that it's US doing it.
Second, there is no "near" oversupply. You are either in oversupply or not based on supply-demand balance. There is "soon to be oversupply" or "projected to be in oversupply". If revenue is growing but profit is falling then it's more about costs and competition but not necessarily not enough demand.
