CARBIS BAY, England (AP) - The United States plans to push democratic allies on Saturday to publicly call out China for forced labor practices as the Group of Seven leaders gather at a summit where they will also unveil an infrastructure plan meant to compete with Beijing’s efforts in the developing world.The provocative proposal is part of President Joe Biden’s escalating campaign to get fellow democratic leaders to present a more unified front to compete economically with China in the century ahead, according to two senior administration officials who briefed reporters on the condition of anonymity because they were not authorized to discuss the plans publicly.The officials said Biden wanted G-7 leaders to speak out in a single voice.
