Seven Global will get a 10% share of sales made as a result of the tie-up, with Trinity agreeing to shell out minimum royalties of $3.5 million (£2.28 million) in the first year, rising to $7.25 million in the final year of the partnership.
Trinity, which has been struggling amid a weaker retail market in China, saw its shares jump more than 50% on the back of its new signing.
Trinity said in a statement: "The Directors believe that the personal involvement of Mr David Beckham in the further development of the Kent & Curwen brand under the Licence Agreement will enable the Group to capitalise on the rising popularity of soccer in China, where Mr David Beckham is already a legend."
