Description

Key Takeaways

  • Since early June, the China Coast Guard (CCG) has maintained a continuous presence in waters east of Taiwan. Beijing describes these operations as a response to a joint statement issued by Japan and the Philippines in late May, in which the two countries pledged cooperation to delimit their maritime boundary.
  • Given their duration, these operations differ from past practice, in which CCG cutters appeared east of Taiwan for short periods of time, ostensibly to signal dissatisfaction with the island’s political leadership.
  • On 4 July, the original CCG task force deployed after the joint statement was issued was relieved by two new ships, suggesting that Beijing intends to normalize CCG presence in these waters.
  • Normalized CCG presence east of Taiwan would pose challenges for Japan and the Philippines, as China would likely apply elements of its longstanding East and South China Sea playbook to this new ocean area.
  • Aside from sovereignty patrols, the CCG could be directed to support operations that exercise China’s claimed coastal state rights east of Taiwan. It could, for instance, escort PRC survey and fishing vessels operating in this disputed space. Using a catalogue of non-lethal means, CCG patrol cutters might also obstruct the operations of foreign fishing and survey vessels.
  • Taiwan might face these same challenges, while also being confronted with the prospect that normalized CCG operations east of Taiwan could enable a more rapid transition to quarantine operations.
