Well, if you think that your international taxi women are representative of PRC people as a whole, then perhaps you are correct. On the other hand, what is the attitude of the PRC population to inter-racial marriage? The point of this thread is that attitudes toward inter-racial marriage are more accurate measures of the racism inherent in a culture than is the willingness of taxi drivers to accept passengers of any race who will pay a good fare .....
I remember some sources but can't be bothered to look them up right now. From what I remember, there were 1900 women and 400 men marrying foreigners in Shanghai, a city of 23 million, in 2008. In 2010, there were 1700 women and 250 men marrying foreigners in Jiangsu, a province of 100 million next to Shanghai. The rate of foreign marriages is going up, with the share of increase going from women in the 90's to men in the 00's. The most common marriages for Chinese woman-Foreign man in both provinces is Japanese, accounting for 40%. The most common marriages for Chinese man-Foreign woman in both provinces is Vietnamese, accounting for 20%.
In Guangdong there were 30000 native citizens involved in marriages to foreigners, the ratio was 2:1 for women:men. Guangdong's statistics are different; they count Chinese citizens living outside the PRC (Chinese citizens with foreign green cards), Taiwanese, Hong Kong and Macao as "foreigners". People with foreign passports (Non-PRC/ROC/Hong Kong/Macao) made up 10% of the total.
The divorce rate for marriages to Japanese is 30% and the divorce rate for marriages to Canadians is 40%.
If that were the case then why would they have children when they can just use the guy to get a visa and citizenship and then divorce him?
They do that all the time especially the ones in Singapore. From my personal observations as a Chinese in the US, Chinese in the US (Not Chinese-Americans) do not usually go for whites. This is because they are usually rich, highly educated, or both so do not see marriage to foreigners as a visa ticket. The uneducated can't go and they can't speak English well enough and there's a deep cultural barrier for both rich and unrich.
Singapore has much more relaxed immigration rules so the less educated can go there, and they will see marriage as a ticket to Singapore PR. In addition, Singapore also speaks Chinese and has Asian culture so there's no culture or language barrier.
My estimate is, for every culture, the culture/language barrier can increase the obstacles for immigration by a factor of 3-4 times vs. GDP. That is to say, another country has to be over 3-4x richer than the native one to be attractive for immigration. That's why Chinese immigration started dropping since 2009; China finally became only 3x poorer than other East Asian countries. However, Indian immigration is skyrocketing upwards. That also explains why Russia is losing whites to Western Europe (3x richer), but no longer to Israel (only 2x richer), and attracting blacks and Central Asian migrants.
