We need to hold their hands, encourage them, allow some time, and reinforce and reward any reaching out for teamwork and interaction. As an expat working with Thais, allow them six months to adapt to new working styles. Apply more pressure later. Support and encourage them in every way. Let Thais know that while you are working with them, they are gaining experience, new knowledge, and new skills.
Culture is the accumulation of experience and reflects a nation's weaknesses in many aspects.
Don't only focus on financial aspects. Study what makes us unique and so different. For example the poorly educated upcountry Thai, the educated Thai and the government official will all think differently. Embassies and Chambers of Commerce should coordinate in campaigns to encourage mutual interests between Thais and expats to boost awareness of the social contribution of foreign investments to the country. They should also organize education programs for expats to provide a course of learning in Thai religion, Thai culture and Thai history.
