Shan State Eastern Special Region 4 (Burmese: ရှမ်းပြည်နယ်အရှေ့ပိုင်း အထူးဒေသ(၄),[2] Chinese: 缅甸掸邦东部第四特区), commonly known as Mongla area or Lesser Mongla area, is a special region administrated by Peace and Solidarity Committee (PSC) of Shan State-East.

Since its active involvement into casinos and endangered wild-animal trafficking, it has been an issue for the Chinese government, which closed the Port of Daluo [zh] several times.

This special region is notorious in southwest Yunnan as they send casino advertisement spam SMS to Chinese cellphones.

Mongla, Mengla or Meungla are different Romanization of the same Tai word, both the e and the o here should be pronounced like the Scottish accent pronunciation of u in bucks.

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