“China has always had an opposition to foreign interference in its domestic affairs, of course, and also in regional affairs, and India, although it’s part of Asia, is perceived as an outside actor in terms of the South China Sea,” said Jonathan Spangler, director of the South China Sea Think Tank in Taipei.

“China and India have quite a complex relationship,” Spangler said. “They have their own territorial disputes along their land borders, and that’s been true for a long, long time.”
