Thailand and
Cambodia on 14 November 2014. She presented her credentials to then-Crown Prince
Maha Vajiralongkorn, representing
King Rama IX, on 4 September 2015. As an ambassador, it was one of Tasneem's priorities to strengthen
religious tourism between the two countries. Md Nazmul Quaunine took over for Tasneem as the high commissioner to Thailand on 23 October 2018.
The United Kingdom, Ireland, and Liberia On 30 November 2018, Tasneem was appointed
high commissioner to the United Kingdom and an ambassador to Ireland and Liberia, succeeding
Md Nazmul Quaunine. She was the first woman appointed to the position. On 1 May 2019, Tasneem attended a reception at
Buckingham Palace, where she presented Quaunine's
letter of recall and her
letter of credence to
Queen Elizabeth II. During the meeting, Tasneem wished the Queen good health and prosperity, and requested that two forests in Bangladesh (one of which being
Lawachara National Park) be included under the
Queen's Commonwealth Canopy. The Queen, in turn, praised Bangladesh's economic growth and empowerment of women. On 21 November 2019, Tasneem met the Irish president,
Michael D. Higgins, at the
Áras an Uachtaráin in Dublin, Ireland. She thanked Higgins for his support of the Bangladeshi diaspora within Ireland. Higgins admired Prime Minister

Rohingya refugees. Tasneem also invited Higgins to open an Irish embassy in
Dhaka and to frequently hold bilateral talks to improve relations.

United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP). There, in May 2016, she helped table a resolution based on Sheikh Hasina's
blue economy policies. It was titled "Regional cooperation in Asia and the Pacific to promote the conservation and sustainable use of the oceans, seas and marine resources for sustainable development". Australia, India, and Sri Lanka co-sponsored it. After several rounds of negotiations, it passed unanimously. Tasneem is also Bangladesh's representative to the
International Maritime Organization. ==Awards==
