Djokovic must abstain from political messages at French Open, sports minister says

French Sports minister Amelie Oudea-Castera said Wednesday that Novak Djokovic's political message about Kosovo was "not appropriate" and warned the former top-ranked Serb player that he should not do it again.

Speaking on TV station France 2, Oudea-Castera said French Open director Amelie Mauresmo spoke with Djokovic and his entourage to insist on the principle of "neutrality" on the field of play.

"When it comes to defending human rights and bringing people together around universal values, a sportsperson is free to do so," she said. But Oudea-Castera added that Djokovic's message was "militant, very political" and "must not be repeated."

Djokovic has drawn criticism from Kosovo's tennis federation after offering his thoughts on clashes in northern Kosovo between ethnic Serbs and police and NATO peacekeepers.

After a first-round victory in Paris on Monday, Djokovic wrote in Serbian on the lens of a courtside TV camera: "Kosovo is the heart of Serbia. Stop the violence."

Kosovo's tennis federation said Tuesday that Djokovic's comments were "deplorable" because he was stoking tensions between Serbia and Kosovo.

The International Tennis Federation has not opened a disciplinary case.

"We received a letter from Kosovo which we have answered," said ITF president David Haggerty. "But essentially we have forwarded their letter to the French federation, to the French Open, it's their tournament, and to the ATP who have the rules — the two of them together have the rules and regulations for the event."

Haggerty added that "athletes have to be careful on their political views. Sports and politics is what we have been talking about and we really want to keep them separate."
