BusinessWorld August 5, 2021 | 2:59 pm Official White House Photo by Adam Schultz WASHINGTON â US President Joseph R. Biden, Jr.âs administration is preparing an overhaul of arms export policy to increase the emphasis on human rights, a departure from former President Donald J. Trumpâs prioritization of economic benefits to US defense contractors, four people familiar with the initiative said.  Defense companies and activists scrutinize such policies for insight into the administrationâs posture as it balances the commercial interests of exporters like Lockheed Martin Co. and Raytheon Technologies against the countryâs stated commitment to human rights.  Two State Department deputy assistant secretaries will brief congressional staff on Mr. Bidenâs draft Conventional Arms Transfer (CAT) Policy on Friday, said two of the people familiar with the situation, with a formal unveiling expected as soon as September. Â
