Lone Dencker Wisborg was born on 31 January 1966 in Brønderslev, Denmark.[1] She grew up in Brønderslev in Northern Jutland, with her mother, father and an older brother four years her senior.[2]
Wisborg began her diplomatic career at the Ministry of Foreign Affairs in 1992 as Head of Section with responsibility for development assistance, assistance to Eastern Europe and international law, a post she held until 1995. She was then assigned to the Danish Embassy in Estonia as First Secretary, from 1995 to 1998. Thereafter, she worked as Head of the International Department and Secretary to the Defence Committee at the Danish Parliament, and subsequently served as Private Secretary to the Minister for Foreign Affairs from 2001 to 2003, and then posted as Deputy Chief of Mission, Royal Danish Embassy in Warsaw, Poland, from 2004 to 2006. She had a brief interlude as Chief Operating Officer (COO) for the Bikuben Foundation, before becoming Head of the Department of Security Policy at the Ministry of Foreign Affairs from 2007 to 2009. From 2009 to 2011, she was Under-Secretary for Global Security.[3][4]
She was recalled to Denmark in 2015, and acted as State Secretary for Foreign Policy, becoming chief operating officer in the Danish Ministry of Foreign Affairs in 2017.[8]
Trump's Greenland proposal and diplomatic tensions
Her tenure involved addressing a proposal by former President Donald Trump to purchase Greenland, a matter discussed with varying degrees of seriousness among Trump's advisers.[12] The proposal encountered resistance, and Kim Kielsen, the Premier of Greenland, firmly stated that the territory was not for sale.[13]Danish Prime MinisterMette Frederiksen described the plan as "absurd."[14] In response to this, President Trump expressed his displeasure and characterized Frederiksen's response as "nasty." Consequently, he cancelled a planned state visit to Denmark scheduled for two weeks after the August remarks.[15][16][17]
In the aftermath of this diplomatic tension, the Prime Minister's Office and the Ministry of Foreign Affairs took efforts to ease the situation. The Ministry of Foreign Affairs and the Danish embassy in Washington engaged their diplomatic connections with top government officials in the United States. During this time, Ambassador Wisborg, played a pivotal role in managing the situation. Having landed in Copenhagen Airport to attend the annual Ambassador's Meeting, she promptly returned to her office and staff in Washington in an endeavour to de-escalate the situation.[18] She rapidly facilitated "several meetings"[19] with the US Department of State and organized a conference call between Frederiksen and Trump, after which Trump's tone shifted considerably, as he began to express a more positive perspective. Speaking to multiple American media outlets, he unexpectedly lauded Frederiksen as a "wonderful woman".[20]
Publicly, she declined to comment on Trump's interest in buying Greenland.[21]
The working paper that Wisborg received from the Danish government before officially beginning her ambassadorship, outlined the direction of the embassy's activities, with a special emphasis on the work between Danish and American soldiers during joint missions. The correspondence on mutual defence policies resulted in Denmark committing to send an additional 500 soldiers to international missions in September 2019, as well as taking over responsibility from Canada for NATO'straining mission for Iraqi soldiers[25]
