Chachoengsao (Thai: ฉะเชิงเทรา, pronounced [t͡ɕʰàʔ.t͡ɕʰɤ̄ːŋ.sāw]) is one of Thailand's seventy-six provinces (changwat), located in eastern Thailand.


Chachoengsao or Paet Riu ('eight stripes') is a province in eastern Thailand.[4] It has a history dating back to the reign of King Borommatrailokkanat in the mid-Ayutthaya period. People originally settled by the Bang Pakong River and along canals. Chachoengsao, Paet Rio, has a history dating back to the reign of King Borommatrailokkanat in the Ayutthaya period. Most people have settled by the Bang Pakong River and along canals. "Luangpho Phuttha Sothon" is a centre of faith of the people of Paet Rio. In the past, Chachoengsao was a fourth class city under the ministry of defence. During the reign of King Rama I, it was attached to the ministry of the interior. During the reign of King Rama V, who changed the administration system, Chachoengsao became a city in the Prachin Buri Circle. In 1916, its status was changed from a city to a province. "Chacheongsao" is a Chong word which means "deep canal". The name "Paet Rio" comes from the story that the city once teemed with giant snakehead fish; up to eight cuts were required on the sides in the making of sun-dried fish.


Chachoengsao province

Neighboring provinces are (from north clockwise) Prachinburi, Sa Kaeo, Chanthaburi, Chonburi, Samut Prakan, Bangkok, Pathum Thani, and Nakhon Nayok. It has a short coastline on the Gulf of Thailand.

The western part of the province is the low river plain of the Bang Pa Kong River, which is used extensively for farming rice. To the east is hillier terrain, with an average elevation of more than 100 metres. In Tha Takiap District is the Khao Ang Rue Nai Wildlife Sanctuary with an area of 674,352 rai ~ 1,078 km2 (416 sq mi).[5]: 3  The total forest area in the province is 804 km2 (310 sq mi) or 15.5 percent of provincial area.[6]


The province has gained a reputation as a centre for recycling potentially hazardous electronic waste (e-waste), despite a June 2018 ban on imports of foreign e-waste to Thailand. China banned the import of foreign e-waste in 2018 also. Since the e-waste ban, 28 new recycling factories, most dealing with e-waste, have started in Chachoengsao province, particularly in the Ko Khanun Subdistrict of Phanom Sarakham District. In 2019, 14 businesses in Chachoengsao were granted licenses to process electronic waste, six of them in Ko Khanun. An official of the Basel Action Network, which campaigns against dumping waste in poor countries, said, "E-waste has to go somewhere, and the Chinese are simply moving their entire operations to Southeast Asia. The only way to make money is to get huge volume with cheap, illegal labour and pollute the hell out of the environment," he added.[7]


The provincial seal shows the main hall of the Sothornvararamvoraviharn Temple. In this hall is the most important Buddha image of the province, known as Luangpho Phutthasothon.[citation needed]

The provincial tree is Peltophorum dasyrachis. The tree was assigned to the province by Queen Sirikit on the 50th anniversary of the coronation of King Rama IX in 2000. The provincial flower is the Yellow Flamboyant (Peltophorum pterocarpum). The provincial fish is the barramundi (Lates calcarifer).

The provincial slogan is "The bountiful Bang Pakong River, the sacred Buddha image of Luangpho Sothon, Phraya Si Sunthon the scholar of Thai language, and the pristine Ang Rue Nai Forest."[citation needed]
