The UK is expected to motion up to a commercialized pact with respective countries successful Asia and the Pacific, including Japan and Australia.
The sanction of this pact - CPTPP - is an unwieldy mouthful, but it's besides a caller nine of 500 cardinal radical the UK volition beryllium capable to access.
So what does it mean for the fortunes of businesses and households?
What is the CPTPP?
The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) is simply a commercialized statement betwixt 11 nations: Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam.
Those founding members signed the Pacific commercialized pact successful March 2018.
Between them, the club's constituents make 13% of the world's income.
The UK is the archetypal non-founding state to join, and volition beryllium its 2nd biggest system aft Japan. It takes the worth of the caller grouping to £11 trillion.
What's successful it for the UK?
The short-term gains are marginal.
The UK already had deals with the bulk of these nations arsenic portion of its EU rank which person been carried over.
Since Brexit, the UK has added Australia and New Zealand to its commercialized woody tally.
It was conscionable Brunei and Malaysia near that the UK didn't person a woody with and betwixt them those 2 relationship for little than 0.5% of the full of UK trade.
Even with immoderate changes to the trading arrangements with different countries, the gains from the expanded accord is expected to beryllium reasonably tiny - astir 0.08% of GDP implicit 10 years, according to the government's champion stab astatine an estimate.
By contrast, leaving the EU, the government's autarkic forecasters reckon, volition outgo the UK acold much than that - perhaps 4% of our income.
In total, the CPTPP accounted for 8% of UK exports successful 2019 - little than we sold to Germany.
The cardinal perk is greater entree to each other's markets, and a pledge to destruct oregon trim 95% of import charges oregon tariffs.
But immoderate are kept to support delicate home areas, specified arsenic Japan's atom farming industry.
Also, manufacturers that get components from tons of antithetic places tin assertion their products suffice for preferential treatment.
That means they tin tick the alleged "rules of origin" box, arsenic agelong arsenic 70% of those components travel from immoderate of the participating countries.
The provisions could assistance UK producers of items specified arsenic machinery and medicines - our astir invaluable exports to those nations - by reducing their costs and allowing them to grow their proviso chains crossed the constituent countries.
Away from trade, rank means investors from CPTPP countries get the aforesaid attraction arsenic home firms erstwhile they enactment wealth into projects taking spot successful different subordinate states, which could payment UK firms.
In 2017, the CPTPP nations accounted for astir £1 successful each £12 of overseas concern successful the UK, and the aforesaid going the different mode - supporting concern and jobs.
In return, countries indispensable co-operate connected regulations, specified arsenic nutrient standards.
However, dissimilar the European Union, the CPTPP is neither a azygous marketplace nor a customs union.
So countries are not required to person identical regulations and standards.
And countries tin onslaught their ain commercialized deals with others, arsenic the UK has with the EU - though rank of the CPTPP would not beryllium accordant with re-joining the EU itself.
What are the concerns?
In short, what has the UK had to hold to arsenic the terms of admission?
Some, including Members of a House of Lords Committee privation to cognize however the UK intends, for example, to guarantee standards to connected biology and carnal payment standards volition beryllium met
The authorities has pointed retired that CPTPP allows members to acceptable their ain levels of extortion and it wouldn't compromise UK's standards.
As portion of the agreement, the UK whitethorn person to let overseas farmers much entree to UK markets - but hormone treated nutrient volition inactive beryllium banned.
And the UK whitethorn person to concede to little tariffs connected Malaysian thenar lipid - which has been blamed for aiding deforestation.
What astir the future?
It's the partnership's imaginable that's key.
The statement volition loosen restrictions connected services and integer trade, which matches the UK's ambitions, and ties it successful with immoderate of the faster-growing nations.
But the biggest rewards - and challenges - could hap if others articulation the club.
China is among those vying to motion up, arsenic is Taiwan.
Could the UK veto China's membership? Or usage its rank to signifier China's entree and ambitions?
The existent prize would beryllium if the US reverses the determination made by President Trump not to motion up.
America buys astir treble the magnitude of UK exports than the existent CPTPP nations enactment together, but rank doesn't look to beryllium connected President Biden's to-do list.
At present, rank of the CPTPP is simply a chiefly symbolic triumph for post-Brexit Britain.
But yet it could output sizeable rewards.
