近期，加拿大和美国都在其政府官网上发布了赴中国的旅行安全提示。由于提示内容较敏感，本站不贴原文，只给出链接，供安全同仁在做差旅安全评估时参考。
此外，本文还分享了两个国际旅行安全预警工具，供大家试用。

另外，美国国务院还专门有个网站提供免费国际差旅安全邮件的服务，叫 Smart Traveler Enrollment Program, 网址：https://step.state.gov/step/
经我们测试，不仅美国公民可以订阅，其实任何都可以免费订阅这个提醒邮件服务。
苹果手机的app store上还有一个免费的国际旅行安全预警应用，叫 Smart Traveler. 大家可以下载试用一下。
不得不承认，美国在这方面做得的确领先全世界，值得各国政府学习。
