4.1.2 Resources
Formerly part of the Golden Triangle, the substitution program to replace opium production with tea, coffee and rice cropping has led to the increase of border trade and commerce. Thus
the economy of the city relies mostly on agricultural resources, small business owners, especially with the extension of tourism. Although over 30 of the land area is officially
classed as farmland, only about 19 is really considered suitable for cultivation – and most of the cultivatable area is located along the Phaholyothin highway, which runs through the
districts of Phan, Muang and Mae Chan and ends in Mae Sai. Moreover through the development of tourism and its associated increasing transport facilities, the city is gradually
becoming a privileged gateway to reach China, Myanmar, Lao PDR, Vietnam and Cambodia. The city currently plays the role of a major transport hub in the whole region, using also the
river as a transportation channel. These dynamics contribute to the urban extension of Muang Chiang Rai over the past years.
