ECON460 International Trade

My requirement is to write a small paper, which is not very difficult but requires absolutely high standards of content

Topic：What types of NTMs (non-tariff measures) exist and how the different types of NTMs affect international trade?

At least 600 words.

The PDF document I uploaded below is some of the knowledge points that may be covered in this small paper. Please make sure to read it before starting work.
