The Thai Chamber of Commerce chairman says 1 October 2026 will be the launch day of a campaign asking businesses to stop paying under-the-table money, as part of the Zero Corruption drive. He says the government should enforce existing laws more strictly on smuggled, mis-labelled and identity-abused goods, and cut discretionary steps. No new penalties or rules were announced in the article. For an SME, the practical point is to review any informal payments to officials or intermediaries before the campaign starts, and expect tighter enforcement on food and industrial imports at retail.
