Next Generation 5G and the US-China Cellphone War
 
Updated, December 20, 2018
The unspoken US policy objective behind the arrest of  Huawei CFO Meng Wanzhou on trumped up charges, consists in breaking China’s technological lead in wireless telecommunications. 
What is at stake is a coordinated US and allied intelligence initiative to ban China’s Huawei Technologies Co. Ltd from the “next generation” state of the art 5G global mobile phone network.
The intelligence operation is led by “Five Eyes”, a so-called “intelligence-sharing alliance to combat espionage” between the US and its four (junior) Anglo-Saxon partners: UK, Canada, Australia, New Zealand.  
Western media tabloids repeatedly refer to legitimate “national security concerns” as a justification for the banning of China’s telecom equipment.
What is at stake is a fierce battle in the global wireless telecom industry. 
Spy Chiefs Meet Behind Closed Doors in Nova Scotia 

On July 17, the spy chiefs from the “Five Eyes” nations travelled from Ottawa to Nova Scotia for a meeting with Prime Minister Justin Trudeau. (who was on a Nova Scotia tour including meetings with NS Premier Stephen McNeil)

The meeting with the “Five Eyes” spy chiefs hosted by Trudeau was held at an (unnamed) coastal resort in Nova Scotia. It was casually described by The Sydney Morning Herald (SMH) as “an informal evening after intense talks in nearby Ottawa”. Nearby?
The encounter with Canada’s Prime Minister was neither informal nor spontaneous. His presence at that meeting served to provide a “political green-light” to the “Five Eyes”  “intelligence campaign” against China:

“Trudeau, …  dropped in on the gathering to share some thoughts about geopolitical threats [from China and Russia].

In the months that followed that July 17 dinner, an unprecedented campaign has been waged by those present – Australia, the US, Canada, New Zealand and the UK – to block Chinese tech giant Huawei from supplying equipment for their next-generation wireless networks.
This increasingly muscular posture towards Beijing culminated in last week’s arrest of Huawei’s chief financial officer, Meng Wanzhou, in Vancouver, over alleged breaches of US sanctions with Iran. (Sidney Morning Herald, December 13, 2018)
