Dubai and US officials are growing nervous at the prospect of another congressional uprising against a second acquisition of US assets by a Dubai-controlled company in the wake of the Dubai Ports World debacle.

A person familiar with the thinking of both the US and United Arab Emirates said officials were concerned that the pending investigation of Dubai International Capital's £700m ($1.2m, €1m) purchase of Doncasters, a privately held British aerospace manufacturer that works on sensitive US weapons programmes, including the Joint Strike Fighter, could provoke a backlash by lawmakers and further damage the relationship between the two countries.
