Huawei warns it may pull out of some countries

The chairman of Chinese tech giant Huawei has warned that his company could shift away from Western countries if it continues to face restrictions.

Huawei has been under scrutiny by Western governments, which fear its products could be used for spying.

Speaking at the World Economic Forum, in Davos, Mr Liang Hua said his firm might transfer technology to countries "where we are welcomed".

He also stressed that Huawei follows regulations wherever it operates.

Huawei makes smartphones but is also a world leader in telecoms infrastructure, in particular the next generation of mobile phone networks, known as 5G.

But concern about the security of its technology has been growing, particularly in the US, UK, Canada, Australia and Germany.
