The Duke and Duchess of Cambridge arrived in style on a colorful decorated Tuk Tuk for a reception hosted by the British High Commissioner for Pakistan, Thomas Drew, at the National Monument of Pakistan.
Kate Middleton dazzled in a bottle green evening gown and the Duke wore eye-catching black Sherwani matching trousers.
The Duke of Cambridge highlighted the country's development in a keynote speech.
Prince William also highlighted the relationship between the UK and Pakistan and also referred to when his grandmother the Queen visited more than fifty years ago.
Earlier, they had met with Prime Minister Imran Khan and toured two educational programs, including a government-run school for students aged four to 18.
The royal couple's visit is the first official one to be made by the royal family to the country since Prince Charles and Camilla visited back in 2006, which will last for five days.
The tour has been dubbed their "most complex ever" by Kensington Palace.
Details of the royal couple's engagements will be released each day amid the heightened security concerns.
Their five-day-tour will largely focus on showcasing Pakistan as it is today, a dynamic, aspirational and forward-looking nation.
They dropped off George, 6, and Charlotte, 4, at Thomas’s Battersea before taking a chopper to RAF Brize Norton, while Louis, one, stayed with nanny Maria Borrallo at Kensington Palace.
The trip also involves visiting programmes, which empower young people, and organisations that help ensure they have the best possible start in life.
