Why do some U.S. companies find it difficult to look for advantages in their own country? As CEOs set their sights on expansion outside their home country, the United States ranked No. 1 at 64% as the country or region where they see the most potential for new market growth worldwide, according to eMarketer, citing stats from KPMG. China followed at No. 2 with 46%. Western Europe as a whole trailed in third, followed by Central Europe and then India.
