By Emily Stephenson WASHINGTON (Reuters) – U.S. banks and retail groups announced on Thursday that they are joining forces to work on cybersecurity, a sign they are trying to move past recent squabbles over who is to blame for data breaches. The Financial Services Roundtable, Retail Industry Leaders Association and several other trade associations said the new partnership would focus on sharing more information on cyber threats and improving technology to protect consumers. Bank and retail industry groups have been at odds for years over cyber issues, but massive data breaches at Target Corp and Neiman Marcus Group LLC have made the dispute more prominent. Thats not something that the two industries are likely to agree upon, Tim Pawlenty, chief executive of the Financial Services Roundtable, said in an interview.
