Something china and japan have in common is

they borrowed and adapted western ideas.
they remained true to their cultural traditions.
they industrialized to improve their economies.
they have a history of strong cultural traditions.

The answer is: They have a history of strong cultural traditions.

Historically, both people from China and Japan were really proud with their own original culture/traditions. This made them adopted policy of isolationism until mid 1900s. They did not like if foreign influence come to their country and started to influence the original culture/traditions that created by their ancestors.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
