It isn’t a secret that Thailand hasn’t really invested in its own infrastructure since before the Asian Financial Crisis, granted we have had the creation of the skytrain, subway and airport, but these were all Bangkok-specific and not throughout the whole country.

Investment made up about a fifth of total spending in fiscal years 2002 through 2009. It dropped to 12.6 percent in 2010 during the global financial crisis, and hasn’t gone back to the 20-percent level since, according to the Office of the Budget Bureau.
The government will allocate 543.6 billion baht for investment in 2016, or about 20 percent of the total, Prayuth said. Of that, about 297 billion baht will be used for investments in rural areas or cities and towns outside Bangkok.
