The China Coast Guard recently stopped a group of Philippine fishermen from trespassing into Huangyan Island. A footage and two photos released over the weekend show the group of fishermen standing on the reef of the island and illegally collecting seashells. The incident occurred in mid-January. Experts say such actions are damaging to the ecological environment and the coral reef. The China Coast Guard took necessary measures to halt these actions in accordance with the law. Their on-site operations were described as professional, reasonable and legitimate.
