(AP-ANSA) - BUDAPEST - U.S. Secretary of State Mike Pompeo was in Hungary on the first leg of a five-nation European tour on Monday, on which he raised concerns about China and Russia's growing influence in Central Europe. Pompeo met in Budapest on Monday with Hungary's nationalist Prime Minister Viktor Orban to stress the importance of promoting democracy and the rule of law. Pompeo said that America might be forced to scale back certain operations in Europe and elsewhere if countries continue to do business with the Chinese telecommunications company Huawei. On Huawei, which is a major player in Hungary, Pompeo said he would make the case to Orban and other officials that doing business with the company comes with significant risks for information security and privacy that could imperil cooperation with the United States. U.S. officials are deeply troubled by Huawei's expansion in Europe, especially in NATO members including Hungary, where they believe it poses significant threats. Ahead of his visits, U.S. officials said Pompeo hoped to reverse what they called a decade of U.S. disengagement in Central Europe that created a vacuum that Russia and China have exploited. Over the course of the past 10 years, the officials said, Russian President Vladimir Putin and Chinese leaders have become much more aggressive in the region and made inroads. (AP-ANSA).
