Sun Dawu sighs sadly when asked about the death of thousands of his pigs, killed by the African swine fever outbreak that has been decimating hog herds across China.
"The pig farm was completely destroyed," he says quietly, fanning himself from the heat and flies on his large Hebei province farm outside Beijing.
More than a year since swine fever began to spread across the country, China's pig farmers are wary of replenishing their stock -- and the disease could become a political and economic liability for the government.
