Germany's Maas described the election decisions as a further infringement of the rights of Hong Kong's citizens.
The Chinese Embassy said the actions were justified and consistent with the one country, two systems framework under which Hong Kong, a former British colony, was handed over to Chinese control in 1997.
The German side's erroneous remarks on Hong Kong and the suspension of the extradition treaty with Hong Kong are a serious breach of international law and basic norms governing international relations and gross violation of China's internal affairs, the embassy statement said.
We firmly oppose them and reserve the right to react further. Germany currently holds the European Union's rotating presidency.
