Vietnam’s total land boundary has a length of 2,883 miles, while its coastline is 2,140 miles long. Mountains cover about 40% of the country's total land area, and approximately 20% is flatland. The northern region is mostly composed of highlands, while the south consists of lowlands. The country's climate varies from region to region due to the diverse landscapes.

Cambodia is a country located in Southeast Asia, which has a total land area of 69,898 square miles and had an estimated population of 15 million in 2016. The country borders Vietnam to the southwest, and the border is 720 miles long. Mekong River passes through the middle of the country thus dividing it into two. Cambodia borders the Gulf of Thailand, Vietnam, Thailand, and Laos. The Cambodia-Vietnamese border was created in 1867 when the French colonialists usurped the western region of the Mekong Delta. The country is shaped like a saucer, and the center of the saucer represents the Central Plains of Cambodia. The central lands are highly fertile and most of the country’s agriculture, rice cultivation being the biggest agricultural activity, takes part in the central lands. Deposits from the Mekong River when it floods make the area highly fertile. The outer regions of the country comprise mountains which include the Cardamom Mountains and Elephant Mountains in the South, and the Dangrek and Annamite Range in the North. Cambodia’s waters have a total of about 60 islands that are administered by the coastal provinces.

In 1997, there was a coup which saw the current Prime Minister Hun Sen take over power.
China is located in East Asia, and borders Vietnam to the north. The Chinese-Vietnam border is 796 miles long and was agreed upon in 1887 and 1889 by the Chinese and the French, although Vietnam claims that China has provoked numerous border disputes since 1957. One dispute is Vietnam's opposition of the Chinese occupation of the Paracel Islands, which occurred in 1974. Both countries lay claim to the islands, and the dispute was left unsolved. China’s terrain is varied, and includes the Himalaya Mountains, the Taklamakan and Gobi Deserts, as well as the Yellow River and Yangtze River.

The Laos-Vietnam border is 1,320 miles long, and was decided upon according to both a geographical and ethnic basis. The Annamite Range was used as a point of reference, and both Laos and Vietnam signed a treaty agreeing upon the border in 1977. The country was named Laos after the Lao people, the ethnic community living in the country. Before colonization, Laos was one of the largest kingdoms in Southeast Asia, known as Lan Xang Hom Kao, which split into three separate kingdoms due to conflict but was later reunited under French colonial rule.

The dispute began with Vietnamese soldiers encroaching on Cambodian territory, resulting in a military standoff between the armies of both countries. The dispute did not escalate to war, as both countries agreed to resolve the issue. The dispute ended through the signing of a new agreement in 2005 that defined the border limits of each country, and Vietnam withdrew its soldiers from the region.
