Vietnamese Foreign Ministry spokeswoman Le Thi Thu Hang

Answering reporters’ query on Vietnam’s response to the act Taiwan had announced earlier, Spokeswoman Le Thi Thu Hang said Taiwan’s move seriously violates Vietnam’s territorial sovereignty over Truong Sa; threatens peace, stability, safety and security of navigation; causes tensions; and complicates the situation in the East Sea (South China Sea). 

The official added that Vietnam demands Taiwan not to repeat the act in the future.
