WA Police are concerned for the welfare of a Chinese woman who has not been heard from by family since late January.
Police are seeking information about the whereabouts of Chen Dong, who arrived in WA from China in November last year.
The 30-year-old woman last made contact with her family on 28 January, stating she was in Perth and had visited Fremantle.
Her family have not heard from her since, which they say is out of character for her.
Ms Dong is approximately 163cm tall, with a slim build and shoulder length black hair.
Anyone who has seen Ms Dong or has information about her location is asked to contact police immediately on 131 144.
