DJ Did the outbreak of African Swine Fever in China open the doors to coronavirusses ? Does Covid19 have a relation with pigs in China ? 

A pig coronavirus is one to watch, but no need to worry at the moment.

As for African Swine Fever, being an asfarvirus it could only exchange DNA with oyher asfarviridae.  So no chance of it mixing with Coronavirus.  (For example, horses breed with horses and occasionally donkeys - their distant cousin.  But they can't breed with lobsters - their relationship is too distant.)  Luckily ASF also requires an arthropod vector  (ticks fleas etc.) or eating the flesh underdone, so although it is endemic in Africa, the risks of a global spread to humans is minimal.
