Influenced by its domestic political，economic condition and the international situation，Cambodia holds a positive attitude towards “The Belt and Road” Initiative of China. With the strong support of China and Cambodia，the two sides have made significant progress in policy coordination，financial integration，infrastructure construction and industrial parks’ development. Meanwhile，China and Cambodia are also facing many obstacles in cooperation，including the single investment pattern，less trade efficiency and comparatively large risk. Therefore，we suggest to build a diversified investment structure，innovate operation mode and actively prevent risks.
