Explanation:

Learning can be defined as a continuous process of acquiring information , knowledge and skills which changes our behaviour permanently.

Learning is not only a formal setting where we go to school to acquire information but we also learn through experience in which we practically get involved in doing things over time we become even better in doing those things.

As we push our self and get driven to get better at something we will give our all to learn it and as a result we may end up even becoming better than our teachers because we approach something new that we don't know with an empty mind and a drive to make sure that we master it ; this is what is happening with Julian.

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.
