Huawei is, along with Sweden's LM Ericsson and Nokia Corp. of Finland, a global leader in developing fifth-generation, or 5G, telecoms.

Huawei is at the centre of US-Chinese tensions over technology and accusations of cyber-spying and violating trade sanctions on Iran.
The company's chief financial officer was arrested in December in Canada on US charges of lying to banks about dealings with Iran. Beijing has detained two Canadians and blocked imports of canola from Canada in what is widely seen as an attempt to compel her release.
