Analysis and Commentary

Up first, in The Diplomat, Tuan Pham wrote a two-part series that the U.S. has irreversibly ceded its influence in the South China Sea and the U.S. can regain the strategic initiative and impose meaningful checks on China’s regional ambitions and strategies. He argues that recent history shows the fluidity of the geopolitical environment in the South China Sea and that strategic shifts in China’s favor need only be temporary But, the U.S. must more deliberately and doggedly reach out to the region and be clear about its security and economic interests. Strategic decline, he says, “is a deliberate choice, not an imposed reality.”

Also in The Diplomat, Joseph Bosco U.S. Pacific Command’s “cool-headed new approach” to FONOPs in the South China Sea, saying the routinization of these patrols is long overdue. But the Navy should go further, he says, and apply the same approach to transits through the Taiwan Strait in order to convey unambiguously to Beijing the U.S.’s enduring commitment to defending Taiwan.

For War on the Rocks, Nathan Beauchamp-Mustafaga, Derek Grossman, and Logan Ma of the RAND Corporation the recent uptick in Chinese strategic bomber flights around Taiwan. The patrols, they say, are the “latest manifestation of top leaders’ longstanding efforts to enhance the PLAAF’s airpower capabilities,” the “ultimate goal [of which] is to deter U.S. intervention in a regional conflict.” They assess that Beijing will continue to use regular bomber flights for strategic signaling purposes and argue that the U.S. should focus not on deterring them, but rather on mitigating the negative effects of these flights, particularly the risk of unsafe air-to-air encounters.

In The National Interest, Koh Swee Lean Collin of the Maritime Security Programme at the S. Rajaratnam School of International Studies whether it is the “preordained destiny of smaller and weaker states like the Philippines and Malaysia, to capitulate to China’s gray-zone tactics.” He concludes the answer is no, highlighting how Indonesia and Vietnam have pushed back against China militarily while simultaneously deepening economic ties. The key, he says, is in “purposefully shift[ing] the onus of escalation to the party contemplating gray-zone tactics through increasing the likelihood of conflict.”

In the South China Morning Post, Sourabh Gupta of the Institute for China–America Studies the lessons the resolution of the Doklam border dispute between China and India might hold for maritime rivals in East Asia as they develop a code of conduct and consultation mechanisms for the South and East China Seas. Gupta says the successful application of China-India boundary management protocols suggests that effective crisis management requires mutual confidence and trust, patience and perseverance, and adaptability rather than rigidity.

Finally, speaking at the Griffith Asia Institute on September 6, Peter Varghese, Chancellor of the University of Queensland in Australia, the future of Australian foreign policy in Asia and how Australia can maximize its strategic interests amidst the battle between the U.S. and China for regional supremacy. Varghese states that the long-term “security of the region cannot rely on the maintenance of U.S. strategic predominance” because while the U.S. “will likely remain the world’s strongest power for decades to come,” it may nevertheless cease to be “the most influential power in the Indo Pacific.” Given the reality of China’s rise, “[i]t is very much in Australia’s interests to have a close relationship with China in as many areas and at as many levels as possible.” Australia, he says, does “not have to make a binary choice between the U.S. and China, at least not unless one insists that we must…[but does] need a sophisticated strategy for dealing honestly with the strategic uncertainties which lie ahead.”
