China-Myanmar relations (Chinese: 缅关; Burma: တရုတ်မြန်မာဆက်ဆံရေး) refers to international relations between the People`s Republic of China and Myanmar. China and Myanmar have active bilateral relations. However, relations between China and Myanmar have recently been hampered by recent ongoing conflicts with Chinese ethnic rebels and Myanmar`s army near the border, as well as recent hostilities against the Chinese in Burma. Like India, China signed an agreement in 1954 with Myanmar`s Prime Minister, U Nu, on five principles of peaceful existence, known as the Panchsheel Agreement. However, the context in which the agreement was signed was severely distorted against Myanmar, as Chinese troops were already in Myanmar and claiming part of northern Myanmar. This has been accompanied by the massive influx of Chinese people to Myanmar, which has changed the demographics of many cities in Myanmar. During World War II, Burma Road was built across the border as an allied supply, as to Chinese troops fighting Japan.  In 1941, after Japan`s invasion of Burma, parts of Burma were ceded to Siam as The Sahrawi territory of Doem, giving China a common border with Thailand, but these territories were returned to Burma in 1946 after Japan`s defeat.    Talks between Burma and China (now under Communist rule) on the border began in 1954, with China interested in more effective control of the region, which was used as a base by Kuomintang troops.  On 28 January 1960, a contract was signed, demarcating most of the border, which was then concluded by a full delimitation contract signed on 1 October 1960, the two parties surrendered small areas along the border.  The following year, both sides demarcated the boundary on the ground.
 China has often adapted diplomatic harassment to prevent the Dalai Lama from meeting with other world leaders. In October 2009, even the then US President, Barack Obama, decided not to meet him, believing that this would have an impact on the US President`s next trip to China. Ladakh and Arunachal Pradesh, the two areas adjacent to the Sino-Indian line of real control, have recorded centuries-old transnational ties, including trade and religious, with Tibet. The Dalai Lama often frequents both territories as part of his religious duties. In this regard, China`s homogenization strategy, whether the border with India has been demarcated or not, would have continued to view its border areas or to perceive areas as a security threat. In the 1950s and 1960s, China continued discussions with at least twelve of its neighbours. China has often said that it is not seeking to develop because it rhetorically claimed to have transformed its land borders into “borders of friendship”. In this context, it may be interesting to consider whether a simple demarcation of borders can bring peace to border areas. The Sino-Myanmar border could be relatively closer to the Sino-Indian line of actual control. China shares a 1,358-mile border with Myanmar.
Like India, Myanmar`s reference point for borders was imperial claims, conventions, agreements and registrations. China has refused to respect imperial conventions or assertions that these are unilateral interpretations of the border. After several rounds of negotiations between the two sides amid a bitter struggle for power in Myanmar, the two countries agreed on a border in October 1960. It seemed that pragmatism had prevailed. There have been territorial exchanges based on geography and administrative ease. There is no doubt that the agreement between the two countries took place to a large extent, but the situation that has followed in northern Myanmar over the past six decades is nothing less than a civil war.
