# China–Laos relations

Chinese-Laotian relations (Lao: ສາຍພົວພັນ ລາວ-ຈີນ, simplified Chinese: 中老关系; traditional Chinese: 中寮關係) refers to the current and historical relationship between Lao People's Democratic Republic and the People's Republic of China.

## History

The Lao kingdom of Lan Xang and its successor states were tributaries of Ming and later Qing China. In the late 15th century, the Chinese backed Lan Xang against their common rival, the Vietnamese. Chinese traders operated in Lan Xang like any other Southeast Asian country, however, Lan Xang also proved to be important as a participant in the Tea-Horse Road trade. Relations between the two states were re-established in 1953 with the Republic of China (Nationalist China or Taiwan) as the sole legitimate government of China. On 25 April 1961, Laos switched recognition to the PRC government in Beijing. However, on 16 May 1962, the royal government severed diplomatic relations with the PRC and restored relations with the Republic of China. Recognition was changed again in 1975 when the new Lao communist government re-established relations with the PRC.

## Economy

Relations have consisted of trade and aid, largely focused on road construction in the northern provinces of Laos, without directly challenging the interests of Thailand or Vietnam in the central and southern regions. However, Vietnam's invasion of Cambodia in December 1978 to unseat the Khmer Rouge regime provoked China into a limited invasion of Vietnam—approximately nineteen kilometers deep—to "teach Vietnam a lesson." Laos was caught in a dangerous bind, not wanting to further provoke China, but not able to oppose its special partner, Vietnam. The Laotian leadership survived the dilemma by making slightly delayed pronouncements in support of Vietnam after some intraparty debate and by sharply reducing diplomatic relations with China to the chargé d'affaires level—without a full break. The low point in China-Laotian relations came in 1979, with reports of Chinese assistance and training of Hmong resistance forces under General Vang Pao in China's Yunnan Province. China remains Laos' largest creditor, accounting for approximately half of Laos' government debt as of 2023.

Like China, Laos is a major supporter of the Pan-Asian Railway, given its desire to move from a land-locked economy to a land-linked economy.$^{:50–51}$

## Government

This hostile relationship gradually softened, however, and in 1989 Diplomatic and party-to-party relations were normalized, and Prime Minister Kaysone Phomvihane paid a state visit to Beijing. In 1991 Kaysone chose to spend his vacation in China rather than make his customary visit to the Soviet Union. Trade expanded from the local sale of consumer goods to the granting of eleven investment licenses in 1991—including an automotive assembly plant. Following the establishment of the Laotian-Chinese Joint Border Committee in 1991, meetings held during 1992 resulted in an agreement delineating their common border. China's commercial investments and trade with Laos expanded quietly, but not dramatically, in 1993 and 1994.
