Explanation:

If you stop paying on a loan, you eventually default on that loan. The result: You'll owe more money as penalties, fees and interest charges build up on your account. Your credit scores will also fall.

Failure to pay the IMF would entitle some of Greece's other creditors, including the European bailout fund, to declare a default. They would then have the option to demand immediate repayment of all their loans, a process known as acceleration. Other lenders could then follow suit. Each creditor decides on its own.

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.
