EU said they will buy lots of Soy Beans. China wanted to hurt our farmers by adding Soy Beans to their tariffs against America.
So EU buying Soy Beans takes pressure from China off our farmers.
Additionally, China is in a situation where they must import soybeans, and if they are not buying pork, they'll need even more feed to raise more. At worst, Brazil and Argentina (both big producers of soybeans, not as big as the US) will buy US soybeans and transship them to the Chinese market.
