African swine fever (ASF) outbreaks which originated from Africa were chronologically reviewed with emphasis on how they were spread to Europe and the other continents. In 2007, ASF suddenly appeared in the countries in the east end of the Black Sea including Russia. As the disease has been well established in Russia, the strategies for ASF should be planned to fight against its risks from two continents, Africa and Russia (Eurasia). It will be extremely difficult to prevent the entry of ASF-infected wildlife from the countries that share land borders. Special attention should be paid to the fact that more than 50% of the swine population of the world is located in China. Feasibility studies should be performed to separate them from infected boars and feral swine by reinforcing barriers such as the Great Wall of China by adding wire walls and new electro-devices.
