AMBALANTOTA, Sri Lanka (AP) — Sri Lanka government supporters have attacked protesting Buddhist monks and villagers with clubs as they marched against what they say is a plan to take over private land for an industrial zone in which China will have a major stake.

Police intervened and separated the attackers Saturday but a scheduled opening of the industrial zone by Prime Minister Ranil Wickeremesinghe was held up due to the unrest.

The government has signed a framework agreement for a 99-year lease of the Hambantota port with a company in which China will have 80-percent ownership. Officials also plan to set up the nearby industrial zone where Chinese companies will be invited to set up factories.
