Hello,
I know Wik is not the most reliable source, but I just read this:
After the German invasion, to administer the economic blockade of Germany, the British Ministry of Economic Warfare was established on September 3, 1939. By April 1940, Britain realized that blockade appeared not to be working because of "leaks" in blockade with two major "holes" at the Black Sea and Mediterranean provided by several neutral countries, including Italy. Reaction of neutral states to new Anglo-French blockade measures imposed against Germany tinder in late November 1939 - that all German goods of German origin or German ownership found on neutral ships would be seized in retaliation for illegal German use of mines - were harsh. All neutrals affected by the measures had protested and Germany was urging them to take joint countermeasures. Belgium, Holland, Denmark, Sweden, Norway, Japan, and Iran have lodged protests with England. Furthermore, a spokesman of the Japanese Foreign Ministry threatened countermeasures in case the British action should damage important Japanese interests. The Brazilian Foreign Minister has stated that in all probability the Inter-American Neutrality Commission, which is meeting shortly in Rio, will decide to protest against the tightening of British blockade regulations.

I'm wondering what exactly happened, since I already read in many sources the contrary regarding the blockade.
