The April 1961 CIA-led invasion of Cuba to topple Fidel Castro that proved to be a total failure when, of the invading force of 1,400, 1,100 were captured and more than 100 killed was the Bay of Pigs Invasion.

Explanation:

On April 17, 1961, a force consisting of 1,500 exiled Cubans attempted to invade Cuba to overthrow the Castro regime by landing on the Bay of Pigs. The invasion attempt was a failure, and the force was defeated by Castro's troops after three days. 100 exile Cubans had been killed, and the remaining 1400 were imprisoned. The main reason they were defeated lay in the expectation of assistance from the United States in the form of bombers. The bombers had been disarmed to look like civil aircraft, which gave them a good camouflage.

The bombers failed to destroy all of Cuba's aircraft. Later attempts with planes that would bomb the remaining planes in Cuba also failed, as the plan was instead shot down by Castro's troops. The US government initially withdrew from intervention but then bought the exiled Cubans back from Castro's hands.  

The invasion force had been recruited among Cuban Castro opponents who lived in exile, especially Florida. There it was equipped, trained and financed by the US CIA.

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.
