從貿易戰走向熱戰
- 相較於經濟施壓,軍事與外交層面的嚇阻與保證相對較為可行。但是經濟脅迫也可能反過來削弱嚇阻與保證的效果。
- 過往幾任美國政府均致力於對中國進行經濟與科技圍堵,甚至推動供應鏈與中國脫鉤。
- 川普第二任期更加速與中國的經濟脫鉤,希望減緩中國的經濟與軍事成長。然而,美國也因貿易戰承受經濟壓力,被迫與北京展開談判,並暫停部分關稅措施。
- 北京方面將美國的經濟與科技圍堵及脫鉤視為和平共存破裂的象徵,更不信任美國,甚至開始挑戰美國捍衛全球貿易的正當性,並加速中國內部推動經濟與科技自給自足。
- 美國的貿易戰策略無法阻止中國的長期軍事發展,中國成功在低成本條件下推動解放軍現代化,同時兼顧經濟成長。此外,若中國認為軍事衝突能比貿易戰帶來更多戰略利益,情勢恐將從經濟對抗升高為軍事衝突。
- 唯有足夠的保證措施,才能提升中國維持現狀的意願。因此,美國應考慮停止或扭轉經濟脫鉤的政策。維持與中國經濟互賴,並與盟國協調制裁機制,也能讓美國在面對台海危機時,有更多籌碼制裁中國。
- 不過,為了控制過度依賴中國的程度,美國仍須限制關鍵進口來源,並分散進口供應來源以強化供應鏈韌性。
美國有許多專家將「嚇阻」與對中強硬劃上等號,但這無助於實質提升台灣的安全。美國應低調加強軍事部署,在外交上保持謹慎,並維持美中經濟互賴與韌性間的平衡。
From Trade War to Shooting War
- Deterrence and assurances in the military and diplomatic aspects are relatively feasible compared to economic pressure. Furthermore, economic coercion can undermine deterrence and reassurance efforts.
- Previous U.S. administrations have pursued economic and technological containment against China, even decoupling from China-related supply chains.
- The second Trump administration hastened economic decoupling from China, hoping to slow down China's economic and military growth. However, the U.S. paused its economic tariffs after suffering financial pains, which forced the administration to negotiate with Beijing.
- Beijing will view the U.S. economic and technological containment or decoupling as an indication of a failure of peaceful coexistence. Consequently, Beijing will mistrust the U.S. more and challenge it as the defender of global trade. It will also hasten China's pursuit of economic and technological self-sufficiency.
- The U.S. trade war strategy could not hamper China's long-term military growth because China modernized the PLA at historically low costs and balanced it with economic development. Furthermore, it will risk escalating the trade war into a military conflict if China perceives the latter as more appealing.
- Only adequate reassurances from the U.S. could increase China's will to maintain the status quo. Therefore, the U.S. should reverse or stop economic decoupling from China. Maintaining economic interdependence and coordinating sanction measures with allies will also give the U.S. more leverage when sanctioning China in case of a Taiwan contingency.
- However, to reduce its reliance on China to an acceptable level, the U.S. should limit its reliance on critical Chinese imports and diversify its import sources.
Many experts in the U.S. equate deterrence with a hard-line posture against China, but this will not meaningfully amplify Taiwan's security. The U.S. should enhance its military readiness silently, exercise caution in diplomacy, and maintain a balance in economic resilience and interdependence with China.
