Mengla County (simplified Chinese: 勐腊县; traditional Chinese: 勐臘縣; pinyin: Měnglà Xiàn; Tai Lue: ᦵᦙᦲᧂ ᦟᦱᧉ ᦶᦉᧃᧈ, Mueang La; Burmese: မိုးလား, Lao: ເມືອງລ້າ; Thai: เมืองล้า) is a county under the jurisdiction of the Xishuangbanna Dai Autonomous Prefecture, in far southern Yunnan province, China.

Thus, to differentiate Mengla County in China and Mong La Township in Myanmar, the locals call the former Greater Mengla/Mongla while the latter Lesser Mongla/Mengla.

[4] Xishuangbanna Tropical Botanical Garden, of the Chinese Academy of Sciences (CAS), is located in Menglun in Mengla County, covering an area of more than 1000 ha.

[6] Mengla has a humid subtropical climate with monsoonal influences (Köppen Cwa) closely bordering on the tropical savanna climate (Köppen Aw) with strong monsoonal influences.

However, high temperatures reach their peak in April before the onset of the monsoon from the Indian Ocean.
