CHINA
The Sikh presence is more of historical importance. Sikh policemen were a unique institution. The Shanghai police was majority Sikhs at one time. Sikh soldiers, as a part of British Indian Army, played key roles in several campaigns in China. All Sikhs left the country post 1949 revolution. There are some new Sikh immigrants slowly moving in.

S. KOREA
The Sikh migration is of recent origin over last 40 years or so. Most immigrants do not have Residence Permits and hence are vulnerable. There seems to be no signs of the community building long term roots in the country. There is a large Gurdwara in a suburb of Seoul.

JAPAN
There are two disparate migrant groups, one recent quasi-legal in Tokyo area and the other old business focused, well rooted, Sikhs in Kobe area who have been there since before WW II.
