SEOUL—South Korea said on June 5 that North Korea has so far ignored its calls for joint efforts to stem the spread of highly contagious African swine fever following an outbreak near North Korea’s border with China.
South Korea’s agricultural ministry said that blood tests of pigs from some 340 farms near the inter-Korean border conducted through Tuesday came back negative. Hundreds of fences and traps have been installed around the farms to prevent pigs from being infected by wild boars that roam in and out of North Korea.
