The final phase of the expansion of Highway 12 -- which links Thailand with Myanmar and Laos in Tak and Mukdahan, respectively -- has been completed, which the government hopes will boost cross-border economic activities between the three countries.

Government spokesman Anucha Burapachaisri said on Monday that Prime Minister Prayut Chan-o-cha was hopeful that the highway's expansion will bring about economic benefits, especially to those living in Kalasin and Mukdahan in the Northeast.
