Britain's Prince William said the United Kingdom and Pakistan share "unique bonds" in a speech at the country's national monument in Islamabad on Tuesday evening during a five-day visit to the South Asian nation with his wife Kate.
Prince William spoke of the warm welcome and delicious food they had experienced in Pakistan after arriving on Monday evening and visiting local school children and Prime Minister Imran Khan.
"The UK and Pakistan share unique bonds and so it will always be in our best interests for you to succeed," William said at the event hosted by the British High Commission, adding that 1.5 million people living in the UK had Pakistani heritage and the UK was one of Pakistan's top investors. "You can rely on us to keep playing an important role as a key partner and your friend."
The Duke and Duchess of Cambridge arrived at the hilltop monument in a rickshaw painted with the Pakistani and UK flags. Prince William wore a teal sherwani suit, a long dresscoat worn over trousers, while the Duchess of Cambridge wore a dress by British designer Jenny Packham in deep green, the colour of Pakistan's flag.
Foreign policy experts and officials have said the trip, the first by a British royal family member in more than a decade and made at the request of the British foreign office, represented a soft power push, which may help both sides further their diplomatic aims.
It comes as Britain seeks to reinvigorate its foreign relationships as the deadline looms for its departure from the European Union, while Pakistan works to repair its global image to boost tourism and investment.
William also mentioned the looming challenge of climate change to Pakistan, as well as the importance of women having access to education, two themes of a trip which has been described by palace officials as the most complex the couple have undertaken due to security issues. Earlier William and Kate met students at an Islamabad Model College for Girls, discussing education with a group of older students and visiting the classrooms of younger students, admiring their drawings.
As they left, a group of girls sang one of Pakistan's national songs and the couple greeted kindergartners who had lined up to chant "bye bye".
While visiting the school a 14-year-old student told William she and other students were "big fans" of Princess Diana, who died in a car crash in 1997. "Oh that's very sweet of you. I was a big fan of my mother too," he replied.
They then visited the Margalla Hills National Park on the edge of Islamabad, which is under threat from poaching, wildfires, invasive species and littering.
For the morning events, Kate wore a periwinkle blue silk shalwar kameez, the national outfit of Pakistan consisting of a loose tunic worn over trousers. Many on social media and in the fashion industry had been hoping she would don the outfit, which Princess Diana had worn during visits.
The designer, Maheen Khan, said on Twitter: "It is an honour to have been asked to create this outfit for the Duchess."
The Duchess of Cambridge's fashion choices, including a bright green tunic over white pants to meet with the Prime Minister, appeared to echo many of the colours and outfits worn by Diana.
