This is the same situation when Europe and especially America where embarking on huge projects such as rail way buildings and other huge infrastructural projects. The projects used to take many years to accomplish and where manned by many people from all around the empires (as it benefits low wages and so on) Probably these people were married and had children in these countries. This is the same pattern as used to happen in classical eras with big urban centers with high economic activity such as ancient Egypt, Babylon and Rome for example. Today we have New York and London. Maybe Dubai and gulf states have a better recruitment policy to avoid challenges with future integration? even though they have a very bad reputation in regards to subhuman conditions where they specifically hire people to do the particular job without ever giving a residence permit. Even though some of their populations are now outnumbered by 'Foreigners' and has been like that for a good number of years. Then there is the Chinese model, where it practically has Zero immigration and the cheap work force is widely available from people in the countryside. I am not sure which Model works for Europe.
You need to stop talking like you know East Asians well. I don't think you do. There are immigrants in China, I admit not as many as Europe, America, Australia, Canada or New Zealand.
The top five countries of origin were the Republic of Korea (ROK), the United States, Japan, Burma, and Vietnam. Even as immigration is rising, immigrants represent a tiny fraction of the country's population of 1.35 billion. China's economic benefits from immigration are indisputable.
There are even Palestinian communities in China.

I saw a documentary about Palestinians in China, but I don't remember where. I think it was a SBS documentary. The people interviewed said that they feel safer in China than in Palestine. They sell carpet for a living.
Return of Overseas Chinese
The only significant immigration to China has been by the Overseas Chinese, who in the years since 1949 have been offered various enticements to return to their homeland. Several million may have done so since 1949. The largest influx came in 1978–79, when about 160,000 to 250,000 ethnic Chinese refugees fled Vietnam for southern China, as relations between the two countries worsened. Many of these refugees were settled in state farms on Hainan Island in the South China Sea.
North Koreans in China
Another activity viewed as illegal is the influx of North Koreans into northeastern China. Some 1,850 North Koreans fled their country in 2004, but China views them as illegal economic migrants rather than refugees and sends many of them back. This is also due to pressure from North Korea. Many of those who succeed in reaching sanctuary in foreign diplomatic compounds or international schools have been allowed by China to depart for South Korea.
Africans in Guangzhou
Africans in Guangzhou are a sizeable community of black Africans primarily concentrated in Guangzhou, China. Since the country's late 1990s economic boom, thousands of African traders and businesspeople predominantly from West Africa migrated to the city of Guangzhou, creating an "Africatown" in the middle of the southern Chinese metropolis of approximately 10 km2. The primarily male population often set up local businesses and also engage in international trade.
According to official statistics of the PRC government, the number of Africans in Guangzhou has increased by 30-40% each year, and now form the largest black community in Asia. However, as many have overstayed their visas, official figures may be understated. Estimates vary on the number of Africans living in Guangzhou: from 20,000 to over 200,000. This has led to controversies and anger by the local community due to rumors of increasing amount of crimes, including rape, fraud, robberies and drug dealing committed by Africans. Huang Shiding of the Guangzhou Institute of Social Sciences estimates the number of permanent residents of foreign nationality (six months and above) to be around 50,000, of which some 20,000 are of African origin.
Take a look at this:

Everybody is saying that how westernised Japanese are. Well I don't think they want any immigrants at all.
The country has remained relatively closed to foreigners, who make up only 2% of the population of 127m, compared with an average of 12% in the OECD, a club of mostly rich countries.
The no-immigration principle is an institutionalization of the homogeneous-people discourse. The principle basically states that Japan does not accept migrants. Indeed, the M-word (imin in Japanese) is markedly absent in legal, media and popular discourse, where it is replaced by euphemisms such as “entrants” and “foreign workers.” On the policy side, this means that it is necessary to do as much as possible to prevent foreigners in general from staying long or settling down. Tessa Morris-Suzuki argues that this principle has remained relatively unchanged since the first Nationality Law of 1899, which aimed to a) prevent an influx of unskilled labor, and b) restrict access to Japanese nationality.
