Why was the arrest significant The arrest has put further strain on US-China relations.
The two countries have been locked in trade disputes, although a 90-day truce had been agreed on Saturday - before news of the arrest came to light on Wednesday.
Huawei is one of the largest telecommunications equipment and services providers in the world, recently passing Apple to become the second-biggest smartphone maker after Samsung.Canadian Foreign Minister Chrystia Freeland said on Friday that China had been assured that due process was being followed and Ms Meng would have consular access while her case was before the courts.Ms Freeland reiterated Prime Minister Justin Trudeau's claim that Ms Meng's arrest had "no political involvement".Who is Meng WanzhouBy TheIndianSubcontinent Monitoring Meng Wanzhou, 46, joined Huawei as early as 1993, when she began a career at her father's company as a receptionist.
After she graduated with a master's degree in accountancy from the Huazhong University of Science and Technology in 1999, she joined the finance department of Huawei.She became the company's chief finance officer in 2011 and was promoted to vice-chair a few months before her arrest.Ms Meng's links to her father, Ren Zhengfei, were not known to the public until a few years ago.In a practice highly unusual in Chinese tradition, she adopted her family name not from her father but her mother, Meng Jun, who was Mr Ren's first wife.
Does Huawei concern the WestSome Western governments fear Beijing will gain access to fifth-generation (5G) mobile and other communications networks through Huawei and expand its spying ability, although the firm insists there is no government control.Japan is expected to ban government use of products made by Huawei and ZTE over cybersecurity concerns, local media reported on Friday.
It would follow moves by New Zealand and Australia to block Huawei.
US National Security Adviser John Bolton said his country has had "enormous concerns for years" about the practice of Chinese firms "to use stolen American intellectual property, to engage in forced technology transfers, and to be used as arms of the Chinese government's objectives in terms of information technology in particular"."Not respecting this particular arrest, but Huawei is one company we've been concerned about," he said.
What are the Iran sanctionsUS President Donald Trump last month reinstated all the US sanctions on Iran that had been removed under a 2015 nuclear deal.Mr Trump had been fiercely opposed to the deal, which saw Iran limit its controversial nuclear activities in exchange for sanctions relief.The re-imposed sanctions hit oil exports, shipping and banks - all core parts of Iran's economy.Although there are some waivers, US Treasury Secretary Steven Mnuchin has said the US will "aggressively" target any firm or organisation "evading our sanctions".
