Ancient rock paintings have been found in

Spain

Explanation:

The oldest cave paintings in the world are in Spain. In 2012, a group of archaeologists concluded that certain series of cave paintings found in Spain had been painted by Neanderthals, and not by the first humans, as previously assumed. Other scientists complained about the methodology used to date the paintings and doubted that Neanderthals had the capacity for symbolic thinking. Now, thanks to an updated dating technique, scientists have shown once again that Neanderthals are the most likely source of those paintings.

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.
