What is the gap between Chinese and Japanese steel industries among Japanese steel enterprises?

After decades of construction and transformation, large state-owned enterprises in China are higher than those in Japan, such as Shougang Jingtang Iron and Steel Company, Bayuquan Iron and Steel Company of Angang Group, Zhanjiang Iron and Steel Company of Baosteel Group, Fangchenggang Iron and Steel Company of WISCO Group, Hanbao New District of Hegang Group, etc. The quality of ordinary steel products is similar, but the key point is that the mass production of high-precision steel products within 10% is huge. For example: radial tire steel, cable steel, die steel, automobile plate steel, deep-drawing food packaging steel, shipbuilding deck steel, high-pressure pipeline steel, advanced corrosion-resistant structural steel, high-quality wire rope dual-phase steel and so on.
