The China Mail - Trump brings back government by social media

With word of these levies against goods imported from Mexico, Canada and China, Trump sent auto industry stocks plummeting, raised fears for global supply chains and unnerved the world's major economies.

For Washington-watchers with memories of the Republican's first term, the impromptu policy volley on Monday evening foreshadowed a second term of startling announcements of all manner, fired off at all hours of the day from his smartphone.

"Donald Trump is never going to change much of anything," said Larry Sabato, a leading US political scientist and director of the University of Virginia's Center for Politics.

"You can expect in the second term pretty much what he showed us about himself and his methods in the first term. Social media announcements of policy, hirings and firings will continue."

The first of Trump's tariff announcements -- a 25 percent levy on everything coming in from Mexico and Canada -- came amid an angry rebuke of lax border security at 6:45 pm on Truth Social, Trump's own platform.

The United States is bound by agreements on the movement of goods and services brokered by Trump in a free trade treaty with both nations during his first term.

But Trump warned that the new levy would "remain in effect until such time as Drugs, in particular Fentanyl, and all Illegal Aliens stop this Invasion of our Country" -- sowing panic from Ottawa to Mexico City.

Seconds later, another message from the incoming commander-in-chief turned the focus on Chinese imports, which he said would be hit with "an additional 10% Tariff, above any additional Tariffs."

The consequences were immediate.

Almost every major US automaker operates plants in Mexico, and shares in General Motors and Stellantis -- which produce pickup trucks in America's southern neighbor -- plummeted.

Canada, China and Mexico protested, while Germany called on its European partners to prepare for Trump to impose hefty tariffs on their exports and stick together to combat such measures.

- Framing the debate -

The tumult recalls Trump's first term, when journalists, business leaders and politicians at home and abroad would scan their phones for the latest pronouncements, often long after they had left the office or over breakfast.

During his first four years in the Oval Office, the tweet -- in those days his newsy posts were almost exclusively limited to Twitter, now known as X -- became the quasi-official gazette for administration policy.

The public learned of the president-elect's 2020 Covid-19 diagnosis via an early-hours post, and when Iranian Revolutionary Guards commander Qasem Soleimani was assassinated on Trump's order, the Republican confirmed the kill by tweeting a US flag.

The public and media learned of numerous other decisions big and small by the same source, from the introduction of customs duties to the dismissal of cabinet secretaries.

It is not a communication method that has been favored by any previous US administration and runs counter to the policies and practices of most governments around the world.

Throughout his third White House campaign, and with every twist and turn in his various entanglements with the justice system, Trump has poured his heart out on Truth Social, an app he turned to during his 20-month ban from Twitter.

In recent days, the mercurial Republican has even named his attorney general secretaries of justice and health via announcements on the network.

"He sees social media as a tool to shape and direct the national conversation and will do so again," said political scientist Julian Zelizer, a Princeton University professor.
