First of all, let me talk about the relationship between these two companies, both of which belong to China Aluminum Company.
China Aluminum Company (full name: China Aluminum Company); Chinalco International (full name: Chinalco International Engineering Co., Ltd.). Generally, in order to distinguish China Aluminum Company from China Aluminum Corporation, the former is often called Chinalco Group or Chinalco, while the latter is generally called China Aluminum Company or Chinalco.
But these two names, people are often fascinated by the word "international", and think that international must be tall. Actually, Chinalco is more cost-effective than Chinalco.
Finally, if you think it is helpful to you, your praise, comments and forwarding are my motivation. please
