MOSCOW—Moscow is to ban import of all fruits and vegetables from Ukraine starting Wednesday, Russia’s agriculture watchdog said Tuesday.

The ban is a further extension of Russia’s series of trade sanctions against its neighbor. Russia started to erect trade barriers earlier this year as the relations between the two countries deteriorated following mass protests in Kiev, which led to a change of the government in late February.

In its statement, the agriculture watchdog Rosselkhpznadzor cited a lack of labeling on Ukraine’s fruits and vegetables, which it said could be the proof that the goods aren't of Ukraine origin. Moscow said the lack of proper labeling may be a means to help EU producers avoid Russia’s import ban.

In August, Moscow imposed a ban on the import of food, including fruits and vegetables, from the EU, the U.S. and some other Western countries following the sanctions imposed by them against Moscow in response to Russia’s policy toward Ukraine.

Before the announcement, Russia had already banned import of many Ukraine food products, including potatoes, sunflower seeds, corn flower, beer, spirits, sweets and chocolates, canned fruits and vegetables, dairy products, and fruit juices,
