CNBC's UK Exchange newsletter: Can UK trade come up Trumps?

Donald Trump is the archetypal U.S. president to person been honored with two authorities visits, thing not adjacent bestowed connected Bill Clinton, George W. Bush oregon Ronald Reagan — each two-term presidents who enjoyed lukewarm relationships with the British premier curate of the day.

That grant reflects the accidental his sojourn offers to deepen commercialized and concern ties betwixt the U.S. and the U.K., which received notably more lenient treatment from Trump when, successful April, helium unleashed his "Liberation Day" tariffs connected the world.

The U.K. often exploits the monarchy's brushed powerfulness to connection authorities visits to countries with whom it desires deeper commercialized ties.

The precocious Queen Elizabeth II hosted galore heads of state, including China's Xi Jinping, Russia's Vladimir Putin, respective Saudi kings and a fig of French presidents. In his 3 years connected the throne, King Charles III has already hosted the South African, French and South Korean presidents, the Japanese Emperor and the Emir of Qatar.

So "tiara diplomacy" is not new. It is conscionable that, with the U.K. system stagnating, it feels arsenic if much is riding connected this peculiar visit.

It helps that Trump, whose parent was calved successful Scotland, loves the U.K. — thing that could not beryllium said of either Joe Biden oregon Barack Obama, his contiguous 2 predecessors.

This presents a unsocial accidental to triumph favour with Trump erstwhile commercialized and diplomacy revolve astir the U.S. president successful a mode they person not for decades.

The commercialized and concern constituent of authorities visits has accrued successful caller times.

Xi's authorities sojourn successful October 2015 saw immoderate £40 billion ($55 billion) worthy of concern agreements signed, with the Chinese president attending an concern acme astatine Mansion House successful the City with past Prime Minister David Cameron.

The brace besides famously visited The Plough astatine Cadsden successful Buckinghamshire, a pub adjacent Chequers, the state residence of British premier ministers, wherever Xi quaffed a pint of Greene King IPA (Indian Pale Ale).

The pub has since go a magnet for Chinese tourists, portion Greene King itself was acquired for £4.6 cardinal successful 2019 by CK Asset Holdings, founded by Li Ka-shing, Hong Kong's richest man.

Sometimes the visits are much to enactment British concern elsewhere, arsenic successful 2016, erstwhile the Queen hosted Colombian President Juan Manuel Santos de Calderon.

Although determination were agreements signed to trim the taxation load connected companies investing successful the 2 countries, the cardinal constituent was the announcement of £1 cardinal worthy of export concern to enactment British companies engaged successful vigor and healthcare projects successful the Latin American country.

Occasionally, though, commercialized and concern travel 2nd to diplomacy.

Macron's authorities sojourn successful July this year, the archetypal by an EU governmental person since Brexit (the king and queen of the Netherlands visited successful 2018), was an effort to repair relations aft the French president was antagonized by erstwhile Prime Ministers Boris Johnson and Liz Truss, the second adjacent speculating publically whether Macron was a "friend oregon foe" of Britain.

This visit, though, is each astir commercialized and, appropriately capable fixed Trump's emotion of describing events successful which helium is progressive arsenic the "biggest and best," looks acceptable to beryllium immense successful presumption of deals.

At the weekend, it emerged that Nvidia and OpenAI volition denote a associated multi-billion-pound investment successful a information halfway task successful Blyth, Northumberland, which has already been launched by Quality Technology Services, a information halfway steadfast owned by the backstage equity elephantine Blackstone.

Nvidia CEO Jensen Huang, OpenAI CEO Sam Altman and Stephen Schwarzman, the laminitis and main enforcement of Blackstone, are each reportedly accompanying the president to the authorities banquet astatine Windsor Castle.

Others invited are said to see Tim Cook, Apple main executive, and Larry Fink, the laminitis and main enforcement of BlackRock, the plus absorption giant, which is expected to denote a $700 cardinal concern successful U.K. information centers.

These information centers volition necessitate plentifulness of energy, and, to that end, an agreement volition beryllium signed betwixt the 2 governments enabling companies to physique caller atomic powerfulness stations successful some countries much quickly.

These see plans by X-Energy, the Maryland-based atomic reactor and substance plan technologist and Centrica, the genitor of British Gas, to physique up to 12 precocious modular reactors successful Hartlepool, County Durham, successful the northbound eastbound of England. It could besides perchance supply an accidental for Britain's Rolls-Royce, which is readying to physique tiny modular reactors astatine home, to bash truthful successful the U.S.

And the announcements person kept coming. Monday brought quality that Blackstone volition treble its £100 cardinal concern into the U.K. during the adjacent decade, portion yesterday saw Google denote a £5 cardinal investment which volition spot it unfastened its archetypal U.K. information halfway and grow DeepMind, its London-based AI arm, creating much than 8,000 jobs.

The large prize for the U.K. is to found immoderate benignant of "AI sovereignty" — thing Huang identified arsenic lacking during his fireside chat with Prime Minister Keir Starmer astatine London Tech Week successful June. This is besides accordant with the Trump administration's ambition to merchantability American AI "packages" to allies specified arsenic the U.K. and South Korea arsenic a counterweight to akin offers from China astir AI infrastructure.

Ironically, overmuch of the spadework for these deals was done by Peter Mandelson, who was sacked past week arsenic British ambassador to the U.S. implicit his erstwhile ties to the disgraced financier Jeffrey Epstein.

Any notation of Epstein this week, peculiarly astatine property conferences hosted by Trump and Starmer, volition beryllium excruciating — and a reminder of however these delicate diplomatic occasions tin backfire.

The astir notorious, successful 1978, saw the precocious queen fell down a bush successful the gardens of Buckingham Palace to debar Nicolae Ceaușescu, having already removed thing that the Romanian dictator could bargain from his country pursuing a informing from Giscard d'Estaing, the past French president.

There is besides an apocryphal communicative of a authorities sojourn successful which, during an open-top carriage procession, the queen apologized to her impermanent aft 1 of her horses broke upwind loudly.

The impermanent — immoderate accidental it was the Nigerian person Yakubu Gowon successful 1973, others the French President Jacques Chirac successful 1996 — is said to person replied: "Don't worry, ma'am, I thought it was 1 of the horses."

One hopes the King's horses volition beryllium little flatulent this week.
