Do not put words in my mouth. Do you even understand what I said? Who said anything about justification?I too think the West is doing a mistake by walling itself in. What protectionism leads to is a well known thing. But I also think the West still needs to get denied export revenues for denying export revenues to China.
I very strongly disagree with viewpoints like that of SanWenYu. Because they presume the West needs a justification. The West doesn't. They just sanction if they can. The only reason they haven't sanctioned civilian airliners and COMAC C919 is the fear retaliation for example.
