The five-year-old boy freed by kidnappers in Pakistan after his family paid a £110,000 ransom was "really happy" to be reunited with his father, a spokesman for the British High Commission said.
Sahil Saeed, who was released on Tuesday after being snatched at gunpoint in Pakistan two weeks ago, met Raja Naqqash Saeed at the home of the British High Commissioner in Islamabad.
A spokesman for the commission said: "Everyone was in very good spirits and of course delighted about his return. Sahil was playing football with his father in the garden and seemed really happy."
Members of Sahil's extended family, including his grandmother, were also at the reunion.
Sahil and his father are expected to fly back to the UK, where their family are waiting at home in Oldham, Greater Manchester.
Sahil was on holiday with his father and other relatives in Jhelum in the Punjab region when he was snatched by gunmen on March 4. He was found by locals wandering alone in a field around 15 miles away on Tuesday and handed over to police.
The boy has since been looked after by British officials while his father travelled from the UK.
On Wednesday night details emerged about the abduction and the police investigation, which involved Pakistani, UK, French and Spanish officers.
Spanish police said Sahil's father went to Paris to pay a £110,000 ransom for his release. Surveillance officers watched him make the transfer, saw the recipients divide up the cash, and later swooped on a number of suspects, according to a police statement.
After the youngster was freed, three people - two Pakistani men and a Romanian woman - were arrested when police raided a flat in Constanti, around 60 miles from Barcelona. About £105,000 in cash was also recovered. Two of the suspects were followed from Paris, and all three are due to appear in court in Spain.
