Illgal Myanmar 'wives' return to home country
Pulic security authorities in Xincai County, central China's Henan Province, repatriated six Myanmar women last week, who were illegal immigrants and had married locals.
In the recent two years, "wives" from Myanmar have become an increasingly noticeable presence in some areas of the province.
Poverty is considered a major reason for the illegal immigration of Myanmar women and illegal marriage.
Citing Cai Xiangyang, a Myanmar language expert who worked as an interpreter in the case, the newspaper said in those less developed areas in Myanmar, some Myanmar people hoped to go to China to have a better life through marriage with Chinese.
However, poverty is also a reason why some Henan people were willing to marry Myanmar women.
