Yes, it certainly is a good decision. For example, if we had no protections like customs China would easily subsidize any market they wish to gain monopoly of the market in question. This is happening even WITH protectionism like customs and tolls. Chinas government subsidize stuff like steel production which makes it hard for companies like SSAB in Sweden to compete with them since they sell their steel cheaper than the cost to produce it. How shall countries protect themselves from countries that act like that without protecting their market? It's extremely naive to think that countries that are rough dictatorships will play fair and nice. EU should have A LOT higher customs against countries like China. Trading with them on a fair level gives them too much economic control which is good for us in the short term but incredibly bad in the long term. That is why south park can make an episode like "Band in China" today because we have already given them a lot of control.
