BEIJING (AP) — Politics weighs more heavily on foreign companies in China than it has in nearly three decades. The latest flashpoint was Beijing's fury last week at hotel keeper Marriott and other companies that labeled self-ruled Taiwan a country on websites or customer materials. But companies face pressure on many sides from President Xi Jinping's more nationalistic stance and twin campaigns to tighten the ruling Communist Party's political control and have it play a direct role in business. Businesspeople complain their operations are being hampered by internet disruptions due to Beijing's latest campaign since last year to tighten censorship of what the Chinese public sees online.
