You do have to wonder about the political savvy of Canadian Prime Minister Justin Trudeau and his government. The furious fallout from China over the arrest of a senior telecoms executive is going to do severe damage to Canadian national interests.

Trudeau’s fawning over American demands is already rebounding very badly for Canada’s economy and its international image.

The Canadian arrest – on behalf of Washington – of Meng Wanzhou, chief financial officer of Chinese telecom giant Huawei, seems a blatant case of the Americans acting politically and vindictively. If the Americans are seen to be acting like bandits, then the Canadians are their flunkies.

Wanzhou was detained on December 1 by Canadian federal police as she was boarding a commercial airliner in Vancouver. She was reportedly handcuffed and led away in a humiliating manner which has shocked the Chinese government, media and public.

The business executive has since been released on a $7.4 million bail bond, pending further legal proceedings. She is effectively being kept under house arrest in Canada with electronic ankle tagging.

To add insult to injury, it is not even clear what Wanzhou is being prosecuted for. The US authorities have claimed that she is guilty of breaching American sanctions against Iran by conducting telecoms business with Tehran. It is presumed that the Canadians arrested Wanzhou at the request of the Americans. But so far a US extradition warrant has not been filed. That could take months. In the meantime, the Chinese businesswoman will be living under curfew, her freedom denied.

Canadian legal expert Christopher Black says there is no juridical case for Wanzhou’s detention. The issue of US sanctions on Iran is irrelevant and has no grounds in international law. It is simply the Americans applying their questionable national laws on a third party. Black contends that Canada has therefore no obligation whatsoever to impose those US laws regarding Iran in its territory, especially given that Ottawa and Beijing have their own separate bilateral diplomatic relations.

In any case, what the real issue is about is the Americans using legal mechanisms to intimidate and beat up commercial rivals. For months now, Washington has made it clear that it is targeting Chinese telecoms rivals as commercial competitors in a strategic sector. US claims about China using telecoms for “spying” and “infiltrating” American national security are bogus propaganda ruses to undermine these commercial rivals through foul means.

It also seems clear from US President Donald Trump’s unsubtle comments this week to Reuters, saying he would “personally intervene” in the Meng case “if it helped trade talks with China”, that the Huawei executive is being dangled like a bargaining chip. It was a tacit admission by Trump that the Americans really don’t have a legal case against her.

Canada’s foreign minister Chrystia Freeland bounced into damage limitation mode following Trump’s thuggish comments. She said that the case should not be “politicized” and that the legal proceedings should not be tampered with. How ironic is that?

The whole affair has been politicized from the very beginning. Meng’s arrest, or as Christopher Black calls it “hostage-taking”, is driven by Washington’s agenda of harassment against China for commercial reasons, under a legal pretext purportedly about Iranian sanctions.

When Trump revealed the cynical expediency of him “helping to free Wanzhou”, then the Canadians realized they were also being exposed for the flunkies that they are for American banditry. That’s why Freeland was obliged to quickly adopt the fastidious pretense of legal probity.

Canadian premier Justin Trudeau has claimed that he wasn’t aware of the American request for Wanzhou’s detention. Trudeau is being pseudo. For such a high-profile infringement against a senior Chinese business leader, Ottawa must have been fully briefed by the Americans. Christopher Black, the legal expert, believes that Trudeau would had to have known about the impending plot to snatch Wanzhou and moreover that he personally signed off on it.

What Trudeau and his government intended to get out of performing this sordid role for American thuggery is far from clear. Maybe after being verbally mauled by Trump as “weak and dishonest” at the G7 summit earlier this year, in June, Trudeau decided it was best to roll over and be a good little puppy for the Americans in their dirty deed against China.

But already it has since emerged that Canada is going to pay a very heavy price indeed for such dubious service to Washington. Beijing has warned that it will take retaliation against both Washington and Ottawa. And it is Ottawa that is more vulnerable to severe repercussions.

This week saw two Canadian citizens, one a former diplomat, detained in China on spying charges.

Canadian business analysts are also warning that Beijing can inflict harsh economic penalties on Ottawa. An incensed Chinese public have begun boycotting Canadian exports and sensitive Canadian investments in China are now at risk from being blocked by Beijing. A proposed free trade deal that was being negotiated between Ottawa and Beijing now looks dead in the water.

And if Trudeau’s government caves in to the excruciating economic pressure brought to bear by Beijing and then abides by China’s demand to immediately release Meng Wanzhou, Ottawa will look like a pathetic, gutless lackey to Washington. Canada’s reputation of being a liberal, independent state will be shredded. Even then the Chinese are unlikely to forget Trudeau’s treachery.

With comic irony, there’s a cringemaking personal dimension to this unseemly saga.

During the 197os when Trudeau’s mother Margaret was a thirty-something socialite heading for divorce from his father, then Prime Minister Pierre Trudeau, she was often in the gossip media for indiscretions at nightclubs. Rolling Stones guitarist Keith Richards claims in his autobiography that Margaret Trudeau was a groupie for the band, having flings with Mick Jagger and Ronnie Wood. Her racy escapades and louche lifestyle brought shame to many Canadians.

Poor Margaret Trudeau later wound up divorced, disgraced, financially broke and scraping a living from scribbling tell-all books.

Justin, her eldest son, is finding out that being a groupie for Washington’s banditry is also bringing disrepute for him and his country.
