Two Chinese direct-sales companies made global headlines recently for taking thousands of employees on all-paid tour to separate foreign destinations - Thailand and France.

Both firms, Infinitus and Tiens, are among the top direct-sellers in terms of sales on the Chinese mainland, following international giants like Amway of the United States and Perfect China of Malaysia.

Infinitus (China) Ltd, a Hong Kong-based company that specializes in health care, skin care and household products, recently took its 12,700 employees on a six-night package to Bangkok and Pattaya in Thailand, the Bangkok Post reported on Wednesday.

They are set to travel in groups of 2,000-3,000 each from May 10-26, spending three nights in Bangkok and another three in Pattaya - at four- to five-star hotels. The first group arrived there on Sunday, said the newspaper citing the Tourism Authority of Thailand (TAT).

TAT acting governor Juthaporn Rerngronasa said the company's incentive tour, a boost to the country's low-season market, is expected to generate around 600 million baht ($17.9 million) in Thailand's tourism revenue this year.

China has been Thailand's biggest source of tourists over the past few years, with expectations of six million arrivals from the country this year, according to media reports citing Kasian Watanachaopisut, president of the Thai-Chinese Tourism Alliance Association.
