Mainland Southeast Asia (also known as Indochina or the Indochinese Peninsula) is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand, Vietnam, and Peninsular Malaysia. 东南亚大陆（也称为印度支那或印度支那半岛）是东南亚的大陆部分。它位于印度次大陆以东，中国大陆以南，西临印度洋，东临太平洋。它包括柬埔寨，老挝，缅甸，泰国，越南和马来西亚半岛的国家。 The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. 印度支那（原印度支那）一词是在 19 世纪初创造的，强调印度和中国文明对该地区的历史文化影响。该术语后来被用作法属印度支那（今天的柬埔寨、老挝和越南）殖民地的名称。今天，与东南亚海洋相比，“东南亚大陆”一词更常被提及。 Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as indo-chinois in 1804, and the Scottish linguist John Leyden, who used the term Indo-Chinese to describe the area's inhabitants and their languages in 1808. Scholarly opinions at the time regarding China's and India's historical influence over the area were conflicting, and the term was itself controversial—Malte-Brun himself later argued against its use in a later edition of his Universal Geography, reasoning that it overemphasized Chinese influence, and suggested Chin-India instead. Nevertheless, Indo-China had already gained traction and soon supplanted alternative terms such as Further India and the Peninsula beyond the Ganges. Later, however, as the French established the colony of French Indochina (covering present-day Cambodia, Laos, and Vietnam), use of the term became more restricted to the French colony, and today the area is usually referred to as Mainland Southeast Asia. 印度支那这个名字的起源通常归因于丹麦-法国地理学家康拉德·马尔特-布伦（Conrad Malte-Brun），他在 1804 年将该地区称为印度支那，以及苏格兰语言学家约翰·莱登（John Leyden），他在 1808 年使用印度支那一词来描述该地区的居民及其语言。 当时关于中国和印度对该地区的历史影响的学术观点是相互矛盾的，这个词本身也是有争议的——马尔特-布伦本人后来在他的《世界地理学》的后期版本中反对使用它，理由是它过分强调了中国的影响，并建议使用中国-印度。 尽管如此，印度支那已经获得了牵引力，并很快取代了其他术语，例如进一步印度和恒河以外的半岛。然而，后来，随着法国建立法属印度支那殖民地（包括今天的柬埔寨、老挝和越南），该术语的使用变得更加局限于法国殖民地， 今天该地区通常被称为东南亚大陆。 The countries of mainland Southeast Asia received cultural influence from both India and China to varying degrees. Cambodia, Laos, Myanmar and Thailand are all influenced by Indian culture, only Vietnam is influenced by Chinese culture but still has minor influences from India, largely via the Champa civilization that Vietnam conquered during its southward expansion.[citation needed] 东南亚大陆国家在不同程度上受到印度和中国的文化影响。 柬埔寨、老挝、缅甸和泰国都受到印度文化的影响，只有越南受到中国文化的影响，但仍受到印度的轻微影响，主要是通过越南在南迁期间征服的占婆文明。
