China and the Hong Kong government are at loggerheads again - this time over a huge sewage project.
China claims that the scheme, which is costing hundreds of millions of US dollars, will lead to increased pollution in is own coastal waters.
China and Hong Kong have argued back and forth for the past two years over how much democracy the British colony should have after China resumes sovereignty.
Now China has lashed out at the Hong Kong government over a sewage project aimed at cleaning up Hong Kong's Victoria harbour.
In Chinese, Victoria harbour is known as the \"Fragrant Harbour\" but it has taken on a very different fragrance in recent years with hundreds of thousands of tons of raw sewage pumped into it every day.
The government has now awarded contracts for the first stage of the sewage management project.
But China objects, saying it will damage the marine environment in the Pearl River Delta.
Some local environmentalists agree with the Chinese authorities
\"The project that the Hong Kong government announced is only primary treatment of the water - they haven't introduced the secondary or tertiary treatment. They decided it is too expensive but I don't think Hong Kong is so poor that it can't afford secondary and tertiary treatment.\"

Mr Yeung says the Hong Kong government has neglected the marine environment allowing untreated sewage from apartment blocks like these to flow directly into the harbour.
\"It's terrible, yeh, some experts put some fish in some area of Victoria harbour and they can't tolerate within two minutes, so it is very terrible - in some areas.\"

The government plans to spend hundreds of millions of US dollars to make the harbour 70 percent cleaner by 1997.
One of the most controversial options is an ocean outfall of treated sewage into the Pear River Delta.
Environmentalists and the Chinese government believe this will have a destructive effect on the ecosystem and damage the local fishing industry in the process.
