Travel has dropped by 5.7 percent since 2018. The move comes as the trade war between the two countries continues to heat up, with US companies ending all business with telecommunications giant Huawei after legislation meant companies needed permission to do deals. The Donald Trump administration has called on its allies to prevent Huawei from being involved in telecommunications infrastructure with Huawei being mandated by law to share information with the central government in Beijing.

The US Treasury says the “United States is disappointed” that China has pursued what it perceives to be a “blame game” that misrepresents the negotiations. Mr Geng accused the US of politicising “normal China-US educational exchanges” at a daily briefing with students abroad being urged to review their situation due to tightened visa restrictions. During the 2017/18 academic year, there were 363,341 university students from China studying in the United States. As FT reports, this is about 30 times the amount of American students studying in China, which is about 12,000. Over the last decade, over a million Chinese students have gone to the United States for their higher education.All rights reserved for this news site express.co.uk and under his responsibility
