The chief executives of the three US carmakers will tell President George W. Bush on Wednesday that US energy, healthcare and trade policies are blunting their competitive edge against fast-growing Asian rivals. Mr Bush is to meet Rick Wagoner of General Motors, Alan Mulally of Ford and Tom LaSorda of Chrysler, a division of Germany’s DaimlerChrysler. The get-together, initially set for last spring, will be the president’s first with all three executives.
