On the 12th, the 10th anniversary of the PCA South China Sea ruling, the Ministry of Foreign Affairs issued a statement criticizing China. China's Ministry of Foreign Affairs marked the 10th anniversary of the Permanent Court of Arbitration (PCA), an international dispute arbitration body, ruling that China's unilateral claim to South China Sea sovereignty was invalid. China, which did not recognize the ruling for 10 years, claimed that the PCA's arbitration itself was illegal and that there was Japan's influence in the ruling.
