"China enjoys indisputable sovereignty over the South China Sea islands and our position is based on full historical and jurisprudential evidence," Chinese Foreign Ministry Spokesman, Hong Lei told a media briefing here today.
"Any country engaged in oil and gas exploration activities in this jurisdiction without the approval of the Chinese government constitutes an infringement upon China's sovereignty and national interest and are therefore illegal and invalid," he said.
"We hope relevant countries keep China's claim, position and rights and interest in mind, follow the Declaration on the Conduct of Parties in the South China Sea and Guidelines in real earnest, refrain from unilateral actions that may complicate and magnify the dispute.
Countries outside the region should respect efforts by regional countries to solve this dispute through bilateral negotiations," he said.
Asked whether China expects that India and Vietnam should take its permission for oil exploration, Hong said China's historical and jurisprudential evidence prove that China first discovered the first South China Sea islands and was the first to exercise administration over the islands.
"Since then China has management and control over these islands which form the historical rights of China in the South China Sea.
