Vietnamese fisherman Nguyen Van Loc has been attacked by Chinese coast guard vessels so many times, he has lost count.
One summer day in 2020, while sailing through the Paracel Islands -- resource-rich waters in the South China Sea claimed by both Hanoi and Beijing -- his boat was rammed by a Chinese ship repeatedly until it capsized.
Thirteen of his crewmen were left clinging to a fishing basket in the water, desperately awaiting help.
