Some have already put down their money, presuming things at least won't get worse. Starwood Hotels & Resorts Worldwide ( HOT) W Hotels has opened a glittery tower in Taipei since 2008, while its overseas hospitality rivals pursue hotels in mountainous scenic spots popular with tourists from China. Share prices of Starwood Hotels & Resorts Worldwide have held steady since this time in 2011. U.S. high-tech giants such as Google ( GOOG) and Qualcomm ( QCOM) have also announced massive projects in Taiwan within the past two years. Share prices of both have risen significantly over the same period. Their pro-Taiwan decisions rested in part on the island's economic stability, which depends on firm links with China. Before it started linking up with China, Taiwan had lagged newly industrialized peers such as South Korea and members of the Association of Southeast Asian Nations.

Though they can do only limited business for now, their permits show that the trend still seems to be toward more open relations.
