Amid worsening relations between China and the United States over trade and defense issues, Vietnam becomes part of the complicated conflict over the South China Sea. This was exacerbated by the sudden and mysterious death of Vietnamese president Tran Dai Quang in September. Many have speculated over the cause of Quang’s death, whether it was from an illness or an unnatural cause brought about by political struggle.
Vietnam’s proximity to the South China Sea gives it an important strategic position and makes it an important player in disputes with China over territorial claims. Vietnam also fought a border war with China in 1979.
