Chinese drinks company Wahaha Group said on Wednesday it has not decided whether to take its joint venture partner Danone to court over a high-profile dispute, although it is reviewing that option.

Earlier this year, Danone filed a lawsuit in California accusing Wahaha of breach of contract by using the Wahaha brand on products sold outside their joint ventures.

China's state-controlled Xinhua news agency said on Tuesday that Wahaha would countersue the French food company and seek compensation of up to 5 billion euros ($6.72 billion), citing a company statement.

Wahaha spokesman Shan Qining said on Wednesday, however, that no decision had been made so far on a counter lawsuit.

"We will make a public announcement if we decide to do this," he said.

A public row between the two partners has escalated in recent weeks, with each flinging accusations against the other.

Wahaha has applied for arbitration in China over a trademark dispute with Danone, asking to terminate a trademark transfer contract signed between Wahaha Group and the joint venture of Wahaha and Danone in 1996.

Wahaha said in a statement over the weekend that Danone's investments in several major Chinese drinks companies had hurt Wahaha's performance and it might file a countersuit against the French company for damages of 2 billion to 5 billion euros.

In a tone typical of its recent statements in the increasingly shrill dispute, Wahaha also reiterated its rejection of Danone's claims.

"Listen, Emmanuel Faber," Wahaha said, referring to Danone's choice of new chairman for their joint ventures, which Wahaha refused to accept. "The false accusations will never turn out to be the truth. It is time that you started thinking about your next job."
