As I have no work in the morning and have been reading for the past hour ...I've discovered that Rui Kang are actually owned by a company called China Wah Yan Healthcare Limited link to website - http://www.chinawahyan.com/index.php?CompanyOverview
They appear to own 2 businesses, Rui Kang (Who they took full control of very recently) and another company caller IR Resources who essentially cut down the Cambodian rain forest and sell wood and agricultural products.
Damn it i also found out some other interesting stuff but i've deleted the tabs by mistake. But that group is run by an 'award winning entrepreneur' who's studied at Uni in UK and USA.
