The us president, Donald Trump, will put an end to the Hong kong special handelsstatus.
It says the president at a news conference late Tuesday night local time, according to the AFP news agency.
Trump has signed a law that approves sanctions against banks in Hong kong, which has been in force for years.
the Announcement comes in the wake of a disputed sikkerhedslov, which China introduced in the beginning of this month in Hong kong.
Hong kong will now be treated in the same way as the mainland - no special privileges, no special financial treatment and no export of specific technologies, says Trump.
- Their freedom has been removed, their rights have been removed, adds Trump, with reference to the introduction of sikkerhedsloven.
Hong kong is, according to the Trump no longer able to compete in the free market, and a lot of people will leave the city, he says.
Trump goes on to say, that the sanctions must be seen as a punishment from China, whose acts he calls 'oppressive' against Hong kong's citizens, writes the news agency Reuters.
The new chinese sikkerhedslov for Hong kong prohibits, among other things revolt or attempts at secession. It can give a prison sentence of up to life in Hong kong.
Already the day after the law was in force, were the first persons arrested in Hong kong in order to have broken it.
A number of countries, including the Uk, France, Germany and Japan have asked China to reconsider the law. According to the countries undermines the right to self-determination.
