Crime is rampant actually … it’s on all the social media sites. Not one day passes without major crime happening in addition to the brawls, counterfeit goods, scams….etc… most of these criminals are from the usual - drunken westerner and the usual Chinese criminals who by pass Thai laws from setting up fake business, fake goods, gambling etc… it’s all reported on social media news but not on main media…
It is correct to address crime to attract tourists but Thailand should also understand that the world economy is currently in turmoil and it is not a good rationale for any tourist to consider traveling during this period. Besides Thailand is also facing more competition from Vietnam beach resorts and also neighboring Malaysia and Philippines. Thailand is also getting expensive .. nice restaurants in Thailand are now charging like nice restaurants in Singapore - Eg. wine per glass is 350thb and above for hotels and nice restaurants.
So not one factor decides the tourist numbers…
