An association that speaks for farmers vowed on Saturday to go ahead with a massive rally planned for next weekend, setting the stage for another clash with police.

The move came after police informed the association composed of farmers earlier in the day that they will ban the group from holding a rally in central Seoul on Dec. 5.

Earlier this week, the association notified police that it planned to hold a rally that could draw some 10,000 participants near City Hall next Saturday.

Police warned that those who organize a rally are subject to punishment if they go ahead with the event despite being banned from holding it. Participants of a rally could also face punishment if they defy police orders to disperse.

Still, the farmers' association said its members will go ahead with a rally on Dec. 5 as scheduled. It also said it plans to seek a court injunction to overturn the ban imposed by police.

Earlier this month, tens of thousands of demonstrators took to the streets in downtown Seoul to protest the government's decision to adopt state history textbooks and reform the labor market. The rally later turned violent as some protesters brandished metal pipes and police fired water cannons at them.

President Park Geun-hye has vowed not to tolerate "illegal" demonstrations and instructed officials to come up with strong measures to root out violent protests. (Yonhap)
