重振大国之风是英国政府长久以来的愿望，“全球英国”理念应运而生。自脱欧进程开启以来，特雷莎·梅政府将这一理念融入英国外交战略，虽备受争议，却也有所成效。“全球英国”理念的落实仍处在起步阶段，批评其不切实际、过分乐观的声音不绝于耳。2017年7月到2018年6月，梅政府的外交政策对践行“全球英国”理念既形成了有效的推力，也产生了消极的影响：积极维护开放的全球贸易环境，试图同欧盟、美国、中国等重要贸易伙伴达成自由贸易协定；强化边界，实行严苛的移民政策，有损包容世界的大国形象；主动参与全球治理，承担国际责任，在安全治理、经济合作、对外援助、环境保护方面表现突出；巩固同英语圈国家、美国、欧盟的旧盟友合作关系，拓展或升级同印度等国的新伙伴关系。
To rehabilitate the declining image and rebuild the national confidence of the UK，the concept of “Global Britain” was correspondingly put forward by May government. Since Brexit，the concept of “Global Britain” has been embedded into May government’s diplomatic strategy. In its fledging period，the concept of “Global Britain” inevitably bears criticism and doubts about its ambitious agenda. During July 2017 and June 2018，the policies formulated by May government exerted both positive and negative effects on the performance of “Global Britain”. In order to maintain a free and opening trade environment，the UK government endeavored to negotiate a tailored free trade agreement with the EU，the US and China. Hard border and harsh immigrant policy were in effect undermining the global-friendly image of Britain. The government played a proactive and responsible role in global governance in terms of security，economic cooperation，foreign aid and environmental protection. The UK also intended to enhance close relations with the EU members and Anglosphere countries，and in the meantime it tried to build a new partnership with promising countries such as India.
