plz bid high EC (environmental charge) to china's export companies

I heard us bid high tariffs to iron companies in china
percent of 522, at the hours ago
congratulations wise choice
But most important problem is
very very severe fine dust from china,
as we know. and to move straightly to US
Our allies korea suffers also this problem
How severe? A few weeks ago NASA flight has gone to korea
and began research to find the pollution factor
Therefore, US bid high EC to china s companies
also US should come off than anyone
despite of my bad english expression, thanks for reading my petition
