Police said the two tourists and a friend violated a red-flag warning and swam despite big surf.
The two victims were identified as Wang Xi Dong and Guo Zi Jie.
The survivor, Liu Wei Jie, 21, said he and the two friends swam briefly before his friends disappeared, so he called an emergency police line to seek help.
Rescuers and lifeguards combed the seabed at the beach until dusk but they failed to locate the bodies.
