Abstract: Oil itself has no political attribute, but the possession, control, exploitation and utilization of oil resources as well as pricing of oil products are closely related to international politics and economy. In recent years, China's energy security and economic development have been under constant threat due to its heavy dependence on foreign energy sources. Saudi Arabia, one of the biggest oil exporters with the largest oil reserves in the world,has played an important role in meeting China's energy needs. Given that China and Saudi share a good foundation for cooperation and have complementary energy strategies,the two countries will enjoy vast potential for energy cooperation. This does not, however, mean that the future is bright. Influenced by international economy, the cooperation between China and Saudi is faced with challenges from America, Russia, India and Iran. As such,the article aims to explore possible obstacles in the future energy relations between China and Saudi as well as the possible changes in the international energy patterns by analyzing the global influences. To ensure China's energy security, we suggest that financial cooperation in energy between China and Saudi be strengthened to break the blockade of petro-dollars, that a practical and institutional cooperation framework be established, that China give assistance to Saudi in fighting terrorists and safeguarding national security and keep a close relationship with Saudi and Iran.

Key words: energy security, Petro-dollars, Saudi Arabia, geopolitics, global influence analysis
