China glass price will increase or decrease?

How do you think the glass price in China? It would stop increase and now is the peak? Or it will increase no matter most people complain it?

According the forecast based on current situation, China glass price will increase again by 20%~25% this year. Amazing or not?

The strict environmental protection policy and carbon emission policy have been issued for long time in China. This made to expand the capacity of production is very hard, even impossible. But the demand increase, then supply falls shorts of demand. The continual new measures to lift the economy aggravated the situation. Then the estimation that glass price will increase by 20%~25% in the followed days in 2021, seems possible.

After all, the glass price in China in 1990’s is much higher than now.
