Respect for hierarchy and seniority shapes most professional interactions in Thailand. The traditional wai greeting reflects this directly: the height of the hands and the depth of the bow signal the degree of respect being shown, with more senior individuals receiving a deeper bow and higher hand placement. The title Khun, roughly equivalent to Mr or Ms, precedes a person’s given name, and addressing someone by both title and name is standard practice.
Personal relationships underpin most business dealings. Meetings typically open with a period of small talk covering family, food or travel, and moving straight to business is generally considered abrupt. Trust tends to develop through networking and referral rather than a single introduction, and Thai counterparts often prefer working with people they already know or who come recommended. Reciprocal favours are common and can create informal obligations that outlast the terms of a written contract.
Decision-making in Thai organisations is generally top-down, with senior leaders holding final authority. Group harmony is valued highly, so direct confrontation or public disagreement is avoided even when there is a substantive disagreement to resolve. Administrative processes can be slow and detail-heavy, and consistent follow-up is often required. The BOI has taken steps to ease this for foreign investors through a one-stop service centre covering permits and approvals, though many companies still rely on local consultants or partners to manage the process.
Non-verbal communication carries particular weight. Maintaining composure is important, since visible frustration or anger can damage a relationship in ways that are difficult to repair. The concept of “face” is central to this: public criticism is avoided, and praise is usually directed at the group rather than at individuals, to avoid singling anyone out.
Business dress is formal and conservative, particularly in Bangkok and in meetings with government officials or senior executives. Suits and ties are standard for men, and business suits or conservative dresses for women. English is commonly used as the working language within international companies, but using basic Thai phrases is well regarded as a sign of respect for the local culture.
