Berlin's relationship with Beijing has come under close scrutiny since Russia's invasion of Ukraine, which exposed the German economy's reliance on Russia for energy and made officials wary of a similar dependence on China for trade.Germany has come under particular pressure to take action on China's telecoms gear makers after the U.S. administration this week banned approvals of new equipment from Huawei and ZTE (000063.SZ) because they pose "an unacceptable risk" to U.S. national security.Under that legislation, individual IT components or entire companies can be banned and declared untrustworthy if suppliers make false declarations, do not support security audits or fail to report or patch vulnerabilities promptly.When asked whether it expected a tightening of rules or even a ban in Germany or the European Union, Huawei told Reuters on Friday it relied on constructive and facts-oriented dialogue."Secure use of networks is independent of a provider's country of origin and can only be ensured by means of global standards in international cooperation between industry and regulatory authorities," Huawei said."
