According to the Vietnam Fisheries Surveillance Department between 70 and 75 Chinese vessels of various kinds were gathered around China's illegally-positioned Haiyang Shiyou-981 rig on July 15.
The vessels, which include armed warships, blocked and chased Vietnamese ships while blaring sirens.
At a fishing ground located 34-39 nautical miles from the oil platform, a Chinese coast guard ship coded 31101 frequently followed and harassed the Vietnamese fishing ships.
The Vietnamese fisheries and coast guard forces avoided the Chinese vessels to ensure the safety of fishing vessels engaged in their commercial activities.
They also persistently demanded that China withdraw from Vietnamese waters.
All necessary preparations are being made to protect Vietnamese fishermen as tropical storm Rammasun makes its way across the East Sea.
The storm has affected Vietnamese vessels tasked with executing law enforcement efforts around the $1-billion oil rig.
In early May, China illegally dispatched the rig Haiyang Shiyou-981 as well as a large fleet of armed vessels, military ships and aircraft to Vietnam’s waters and positioned the rig 80 miles inside Vietnam’s continental shelf and exclusive economic zone.
Despite Vietnam’s protests, China expanded the scale of its operations and moved the rig 60 nautical miles deeper into Vietnamese waters.
