Around 100 new jobs are set to be created in Wales through a joint venture between Llangennech-based company Hydro Industries and US company T&T Salvage.
The deal was sealed during a four-day trade mission in San Francisco, where First Minister Carwyn Jones is leading a delegation of 18 Welsh businesses.
Hydro Industries specialises in the design, manufacture and operation of electro-based water treatment products. The deal will see unique products that have been developed and patented in Wales deployed across the United States market.
