Germany is considering ways to block Huawei from its next generation mobile phone network, according to reports.
Berlin is exploring stricter security requirements which may prevent Huawei products being used in its 5G network.
Many countries have pushed against the involvement of the Chinese technology firm in their 5G networks over security concerns.
The networks represent the next big wave of mobile infrastructure.
The Chinese company, one of the world's biggest producers of telecoms equipment, has faced resistance from foreign governments over the risk that its technology could be used for espionage.
Huawei has denied claims it poses a spying risk.
In a statement, the firm said it sees "no rational reason why it should be excluded from building 5G infrastructure in Germany, or indeed in any country in the world."
Germany's interior ministry had previously said it opposes banning any suppliers from its 5G network.
But it may consider stricter security requirements and other ways to exclude Huawei, according to reports.
Such a move would bring it in line with other Western countries.
The US, Australia and New Zealand have all blocked local firms from using Huawei to provide the technology for next-generation 5G mobile networks.
The UK has raised concerns with Huawei, and Canada is also reviewing its relationship with the firm.
On Thursday, China's ambassador to Canada warned of "repercussions" if the country banned the company from its 5G network.
The two countries are embroiled in a diplomatic row.
A court in China this month sentenced a Canadian to death for drug smuggling in a ruling that comes after Canada arrested Meng Wanzhou, a top official at Huawei and its founder's daughter, on a request from the US.
The US is also reportedly investigating Huawei for "stealing trade secrets" from US businesses, and has accused it of contravening sanctions by lying about its business in Iran.
