Political pundits and the Equal Opportunities Commission are calling for calm amid an intensifying conflict with mainlanders.
The month-old furore shows no signs of abating, with a day-old Facebook group set up to oppose a government plan to make it easier for mainlanders to drive across the border drawing nearly 20,000 users.
Meanwhile, the Mannings pharmacy chain apologised over a Lunar New Year promotion that gave coupons to mainland passport-holders only.
Professor Ma Ngok, a political scientist at Chinese University, said discussion on the dispute among Hongkongers had become emotional and irrational, and it would be difficult to end the conflict if the trend continued. 'The discussion should focus on how to solve the problems through policies, if the purpose is to alleviate the tension,' he said. 'But right now, it's difficult for people to discuss rationally. It's getting a bit out of control.'
His colleague, Ivan Choy Chi-keung agreed, saying the authorities should address the tension by doing a policy review. 'The government has always been promoting the city's travel industry, but has failed to look at Hong Kong's capacity when doing so.'
The commission said it was concerned about a newspaper advertisement on Wednesday that described mainland visitors as locusts that consumed resources in the city.
Commission chairman Lam Woon-kwong called for tolerance and rationality. He said the government should adopt effective measures so Hongkongers would continue to enjoy priority in public services.
