China has refused to join the arbitration process initiated by the Philippine government last year. Today, Philippine officials pressed a call for China to join the arbitration as a peaceful and durable solution to the long-raging territorial disputes, which have flared in recent years and sparked alarm across Asia and beyond.
The Hague-based tribunal issued a statement yesterday, giving China until December 15 to submit written arguments and evidence against the Philippine complaint, which questioned the validity of China's so-called "nine-dash" claim, which refers to a rough Chinese demarcation on its official maps of territorial claims that cover virtually the entire South China Sea.
China's separate disputes with the Philippines and Vietnam have worsened recently, especially after it deployed an oil rig early last month in waters also claimed by Hanoi, sparking violent anti-China protests in Vietnam.
