(Reuters) - Russia's consumer watchdog Rospotrebnadzor said on Saturday it might ban imports of wine from Moldova within two weeks, amid a dispute over the two nations' Soviet-era history. Rospotrebnadzor has already barred tens of thousands of bottles of Moldovan wine from sale this month, citing quality problems. A total ban would severely damage a vital sector of Moldova's economy since the country exports to Russia about 20 percent of its total wine production.
