南海是太平洋與印度洋間的重要國際海運航道，因為具有重大的地緣戰略利益，對亞太安全有重大的影響，因此涉入南海爭端的國家眾多。在南海主權的各聲索國中，越南宣稱擁有西沙群島與南沙群島的全部主權，是中國大陸南海爭端中的最大競爭對手；南沙群島周圍近越南、菲律賓、馬來西亞、印尼的海域已有相當量油產，全球貿易有25%經過南海，其中臺灣、日本及南韓的石油輸出線均依賴此航道，漁場亦為周邊國家最重要的漁獲來源，是西太平洋中最具戰略和經濟價值的群島，也是目前國際糾紛最多之處；2010年越南利用擔任東協輪值主席國的機會，刻意引進美、日等區域外勢力，將南海問題導向國際化與東協化，以構建與各大國間的等距平衡交往戰略，藉以抗衡中國大陸，並從中獲得外交自主性。目前中國大陸對南海問題係採取「主權歸我、擱置爭議、共同開發」的政策，但仍積極強化南海戰力與維權執法作為，並堅持「反對區域外國家參與」及「雙方協商」的原則，以獲得最大的優勢。中越南海爭端涉及國際衝突管理與權力平衡，臺灣為南海主權聲索國之一，占有南沙群島的最大島嶼－太平島已60餘年，在面對中國大陸與越南等國積極強化南海經營管理策略及戰略部署的同時，我國更應思考如何強化南海主權作為，積極參與南海競局，以確保國家最大利益

中國與越南的關係源遠流長，自古就是山水相連的鄰邦，由於特殊的歷史、文化和地緣等因素，自古以來，中國就是對越南影響最大的國家。中華人民共和國成立後，從1950年到1990年的40年當中，中越關係經歷了從「同志加兄弟」到「兵戎相見」的嚴重對立又走向改善這樣關係大幅度的改變和劇烈變化。「渡盡劫波兄弟在，相逢一笑泯恩仇」，隨著1991年11月中越關係正常化以來，雙方在各個領域的交往與合作日益發展。1999年2月，兩國領導人確立了新世紀中越關係的發展框架，即「長期穩定、面向未來、睦鄰友好、全面合作」的方針。2002年中共總書記江澤民訪越期間表示，兩國要永遠成為好鄰居、好朋友、好同志、好夥伴。2008年5月底，越共中央總書記農德孟應邀訪問中國大陸時，中越發表《聯合聲明》宣示，雙邊關係提升為「全面合作戰略夥伴關係」。 2010年迎接中越建交60周年，雙方將今(2010)年定為中越友誼年，兩國關係正常化後，在政治關係，領導人互訪頻繁，建立各種對話機制和管道；在經濟合作方面，雙邊貿易迅速擴大，與中共－東協自由貿易區依存日益加深。但在友好合作關係下仍然存在有諸如民族主義興起、領土糾紛、台越關係的影響、貿易不平衡、投資與政治關係不對稱、歷史華僑等，不利於兩國關係發展問題；整體觀之，中越雖存在著矛盾，但可推測兩國未來的關係仍將持續深化，以維持和平、穩定的周邊環境；雙方仍互相抱持高度警覺與戒心；越南將加強與東協及大國關係，以提升對中共談判與對抗優勢；互藉地緣優勢，各取所得；進一步擴大雙邊經貿等方向前進。 / Sino-Vietnam relations can be traced back to ancient times. They have been neighboring countries sharing the same border. Compared with other countries, China has imposed most influence on Vietnam due to their special historical, cultural, and geographical connections. After the founding of the People’s Republic of China (PRC), China and Vietnam relationship experienced dramatic change within years from 1940 to 1990. It started from the period of “comrades plus brothers”, then went to “resort to arms,” and finally improved to current benign relationship. The China-Vietnam relations can be described as “experiences disaster brothers, as soon as meet by chance, their smile vanishes the love and hate.” After the normalization in November 1991, the two countries’ interaction and cooperation in all aspects have been further strengthened. In February 1999, the leadership of two countries established the framework for bilateral relations in the new century, which is “long-term stability, facing the future, good-neighborly relations, and comprehensive cooperation.” In 2002, Jiang Zemin, Chairman of the Communist Party of China, visited Vietnam and noted that two countries would always be good neighbors, good friends, good comrades, and good partners. In the end of May 2008, Nông Đức Mạnh Chairman of the Communist Party of Vietnam, visited China. Two countries made Joint Statement and declared to elevate bilateral tie to ‘comprehensive strategic partnership.’ In 2010, for the upcoming 60th anniversary of Sino-Vietnam diplomatic relations, two countries define the year as ‘China-Vietnam friendship year.’ Since establishing two countries’ diplomatic relation, politically, the leadership of two countries has visited each other frequently. Economically, bilateral trades have expanded rapidly and further relied on China-ASEAN Free Trade Agreement (CAFTA) Zone. Nevertheless, several issues emerge and handicap their cooperation. These issues include the rise of nationalism, territory conflicts, impact from Taiwan-Vietnam relations, trade imbalance, the asymmetry of investment and political conditions, and influence from overseas Chinese. Overall, despite of existing contradictions, the development of China-Vietnam relationship will be continually enhanced so as to maintain a peaceful and stable environment. At the same time, two countries will still be highly cautious of each other. Vietnam will improve its connections with ASEAN and other major states in order to strengthen its advantage on negotiation table against China. Two countries will make the best use of their own geographic advantage and take what they need from their cooperation. Also, they will further expand bilateral economic and trade relations in the future.
