美國總統特朗普(Donald Trump,川普)今年5月訪問北京,與中國國家主席習近平會談後,美中雙方定調建立「建設性戰略穩定關係」,意圖在競爭中尋找可控互動,避免衝突進一步升級。
然而,短短數月內,特朗普在全國電視演說中突然重提「中國干預美國大選」指控;美國隨後以「強迫勞動」為由,對包括中國在內的多個經濟體加徵新的301條款關稅(中國稅率達12.5%),立即引發北京強烈不滿與反擊。
這些舉措背後,雙方各自打著什麼算盤?
多名接受BBC中文訪問的學者認為,目前雙方仍在「管理競爭」的框架內互相試探,真正的考驗將是預計9月舉行的特習會。
五月後的起伏:從「戰略穩定」到相互試探
自五月來,美中互動似乎呈現「一邊推進合作、一邊施壓」的雙軌模式。
兩國高層溝通並未中斷。中國外長王毅與美國國務卿盧比歐(Marco Rubio)在馬尼拉舉行約90分鐘會談,雙方形容為「務實、積極、建設性」。王毅甚至稱今年是中美關係的「大年」。此外,中國外交部副部長馬朝旭訪美、美國聯邦調查局(FBI)局長訪華等接觸也密集展開。
與此同時,摩擦並未停止。
特朗普公開指控北京長期介入美國選舉,中國外交部即刻反駁,並要求華府「停止無端抹黑」。
7月下旬,美國宣布新一輪301關稅後,北京譴責有關措施為單邊行為,但並未立即採取報復,而是重申自身立場與政策底線。
台灣議題同樣持續牽動雙邊關係。
特習會後,美國暫緩一筆對台超過百億美元的重要軍售,台灣立法院在野黨同時又一次封殺對美採購無人機預算。
上週,美國在臺協會(AIT)刊登一則消息,被認為是首度美官方公開台灣海巡署船艦與美國海岸防衛隊船的合影,並稱「支持台灣在海事執法交流等全球議題上做出實質貢獻」。台灣政治評論者鄒景雯稱「這絕對是第一島鏈區域的再一件大事。」
整體而言,5月會談後,美中一方面維持高層溝通、經貿與執法合作有進展,另一方面就台灣、關稅與南海問題仍不斷有所過招甚至摩擦。
專家:雙方仍在管理競爭
美國智庫太平洋論壇(Pacific Forum)兼任研究員藍若思(Elizabeth Larus)向BBC中文表示,特朗普向習近平發出了模稜兩可的訊號。
她指出,一方面,美方對中國在烏克蘭與伊朗戰場上的軍事支持視而不見;另一方面,卻願意討論向中國出售價值數十億美元的美國農產品。
她還說,特朗普也沒有明確回應中國在亞太地區、尤其是台灣周邊與南海的挑戰。
「如果美國將中國視為安全威脅,則需要採取更強硬的軍事手段。」她說。
不過,美國布魯斯金學位秦江南(Jonathan Czin)近日在《外交事務》撰文稱,美中目前的狀態,與其稱為「穩定關係」,不如形容為「相互保證的干擾」(mutually assured disruption)。
他指出,特朗普將美國帶回中東的泥沼當中,使得北京得以透過經濟及軍事等優勢,好整以暇地面對分身乏術的華盛頓。
英國諾丁漢大學中國研究中心蘇利文教授(Jonathan Sullivan)亦持相似看法。
他認為,特朗普在北京會談時已處於相對弱勢,「現在情況更糟了」。他指出,特朗普正在輸掉一場戰爭,更糟的是美國根本無法從中東抽身。
「明顯地,北京樂於看著特朗普盡全力加速美國的衰落,以及削弱美國主導的國際秩序——敵人正在犯錯時,就別去打擾他。」
不過,新加坡獨立國際關係評論員鄧銘杰則提醒,不宜將局勢簡化為「美國分心、中國得利」。
他指出,中國經濟正在放緩,北京並非單純受益,而是以克制態度管理風險。
他還說,北京的回應並非被動,而是精準地告訴華盛頓紅線所在,並選擇在紅線尚未被跨越時不升級,反映出其在制約下仍能以紀律管理關係的能力。
九月特習會將談什麼?
多名學者認為,若9月特習再次會晤,預計重點將是「管理競爭」,而非「解決問題」。
鄧銘杰認為,習近平的優先事項是「爭取時間」,包括延長休戰、在對台軍售上克制,以及在晶片議題上爭取喘息空間。
「雙方都寧願握著最強的牌,而非打出去,因此才會出現休戰與對話機制,而非真正解決。」他說。
藍若思教授則預計,特朗普可能提出中國增加採購數十億美元美國農產品(除2025年10月作出的購買大豆承諾外)、放寬對輝達(Nvidia 英偉達)高端晶片的限制、 人工智慧議題,以及開放霍爾木茲海峽商業航行等議題。兩人也可能討論彼此加徵高額貿易關稅。
藍若思還說,特朗普可能再次提到釋放黎智英,以及中國在伊朗問題上的角色。
專家一致認為,台灣問題仍是美中關係的核心。只要特朗普不批准對台軍售,不直接觸碰台灣問題,關稅或AI晶片的問題,都不會讓習近平九月訪美的計劃生變。
「但特朗普需要一些東西,中國也想要得到些什麼,例如美國公開表態反對台灣獨立。」蘇利文說。
對台灣來說,鄧銘杰強調,美國對台軍售案每多一個月未簽署,台灣就多停滯一個月。他認為,更大的問題不是這筆軍售案本身,而是它所立下的先例,台北需要有自己的戰略應對。
蘇利文則表示,美台戰略利益仍高度重疊,目前尚未到需要恐慌的程度。
「現在也很難做更多推測,因為六週左右的時間,在『特朗普時間單位』裡簡直可以是『永恆』。」

* Potential topics for the September meeting include US purchasing more Chinese agricultural products, easing restrictions on Nvidia chips, AI issues, and commercial navigation in the Strait of Hormuz.
Executive Summary
Recent interactions between the United States and China have involved high-level communication aimed at establishing a "constructive strategic relationship," though this has been punctuated by friction over specific issues. Following discussions in May, there was a visible duality: progress in high-level dialogue concerning trade and law enforcement cooperation alongside ongoing friction regarding Taiwan, tariffs, and South China Sea matters. While official channels maintained contact, public statements involved mutual challenges, such as US accusations regarding election interference and China’s responses to trade measures. Experts suggest that the current dynamic is characterized more by managing competition than resolving underlying disputes.
The upcoming September meeting is anticipated to focus on managing this competition rather than achieving concrete solutions. Potential discussion points include trade relations concerning agricultural products, restrictions on advanced semiconductors like those from Nvidia, developments in artificial intelligence, and the status of maritime freedom of navigation. There is an acknowledgment that the Taiwan issue remains central, but experts suggest the outcome hinges on specific concessions or demands from both sides regarding security interests and perceived threats.
Full Take
The reported shift from a framework of "strategic stability" to mutual probing suggests that the current relationship is fundamentally defined by competitive tension rather than stable alliance management. The observation that the US positions itself relative to perceived threats—as suggested by scholars pointing to China's posture regarding Ukraine, Iran, and the Taiwan region—indicates that diplomatic openings are constrained by underlying security calculations.
The framing of the dynamic as "mutually assured disruption" implies that the risk lies not in direct conflict escalation, but in the cumulative effect of competitive signaling where each side tests boundaries without committing to fixed lines. The assertion from some observers that Beijing is managing risk rather than purely benefiting suggests a sophisticated capacity for calibrated response, demonstrating control over the tempo of engagement.
The pattern here points toward an equilibrium maintained by bounded rationality: parties engage when the cost of inaction exceeds the immediate risk of interaction. For Taiwan, the persistent ambiguity surrounding security assurances—particularly concerning US military support and future policy stances regarding the Taiwan Strait—demonstrates that economic or trade concessions alone are insufficient to resolve core strategic concerns; the calculus remains deeply rooted in geopolitical positioning. What is missing is a clearer understanding of how domestic political imperatives dictate the pacing of external strategic maneuvers when the perceived existential stakes remain high for all involved parties.
