Betting is illegal in China, so thousands of Chinese flock to the relative safety of Maijayang to try their luck at the mafia-run casinos on this Myanmar frontier town.

Shielded by Myanmar's lush green mountains, surrounded by a wall of dense sugarcane fields, Maijayang rises from these ancient lands in Kachin State -- which is effectively run by former rebels -- like a forbidden fortress.

While world leaders condemn a bloody crackdown by security forces against mass protests in Myanmar's main city Yangon and elsewhere, little is taboo in this sinners' paradise.

Business is roaring here, handily located just 20 minutes by motorbike from the border along pot-holed dirt roads that wind through picture-perfect paddy fields.

"Whatever you need we can take care of, gambling, drugs, girls -- all of it can be arranged," a former casino employee surnamed Wang said as he escorted an AFP journalist past Myanmar border guards to Maijayang.

Visas are required to enter Myanmar but are easily bypassed here in Kachin, where the rebel Kachin Independence Organisation and a fragmented coalition of warlords hold sway over an area bordering China's Yunnan province.

After paying the guards, Wang buzzed through the town gates, past rows of low-slung, white-tiled buildings that advertise hotels, restaurants, gems and massage parlours that double as brothels -- all in Chinese script.
