When Titans Clash Season 4 Episode 1

Some EU and US leaders have accused China of overcapacity, and dumping electric vehicles, solar panels, and batteries on the global market, at artificially low prices.

China has hit back, saying that there is no overcapacity in its 3 clean tech industries, and accusing some of these countries of being protectionist. Who is right? Are we about to see a trade war erupt between EU and China, similar to what we had seen between the US and China?
