Baijiu maker Wuliangye Yibin Co Ltd has teamed up with United States liquor giant Brown-Forman Corp to develop new products for emerging markets and counter sluggish baijiu sales business due to the ongoing crackdown on corruption and extravagance in China. Brown-Forman, the Louisville-based wine and spirits producer that owns famous whiskey brand Jack Daniels, has already signed a cooperation agreement with Wuliangye in this regard, said sources.
