Updated at 3.44pm: A group of pregnant women launched a protest over the weekend to express their concern about the abuse of maternity services in Hong Kong hospitals by mainland mothers using these services. The Hong Kong woman are angry that their right to enjoy subsidised maternity services in public hospitals is being undermined by an increasing number of mainland women giving birth here and then returning to China without paying their hospital fees. Ming Pao Daily reported on Monday that about 60 pregnant women ? some accompanied by their husbands ? took part in the protest. They chanted slogans and raised cardboard placards as they marched from the Legislative Council uphill to the Central Government Headquarters on Sunday. They said they had found it increasingly difficult to receive adequate maternity services in recent years as some resources had been diverted to cater for mainland women, the newspaper reported. One protester, surnamed Gei, who was about to give birth to her second child, was quoted as saying she now had to wait nine weeks for a pre-natal check-up. This compared with only four to six weeks a few years ago. Mrs Gei said hospital staff had declined her request for an ultra-sonic examination because her baby was not her first child. ?I asked a nurse why it was so. She only answered me that there were no resources,? she said. An organiser of the protest, who gave her surname as Lau, urged the government to review its policy on maternity wards for local pregnant women. ?If there are insufficient resources for local pregnant women, it should stop women from outside Hong Kong coming to give birth here,? Mrs Lau added. Government figures show the number of mainland women giving birth in Hong Kong?s public and private hospital has increased in the past few years. There is also concern in the territory this is increasing the workload of hospital staff and affecting the quality of their services. Moreover, there are fears the babies ? usually born by illegal immigrants or visitors who are non-Hong Kong residents ? will claim citizenship in the territory. The government is considering ways to discourage mainland women to come to Hong Kong to give birth. These include an increase in hospital charges.
