It's not the first time Harry has visited Angola. The royal is patron of the Halo Trust, a charity Diana championed for years, and he travelled to Cuito Cuanavale in 2013 to see the charity's mine clearance work. During the visit, Harry said, "By clearing the landmines we can help this community find peace and with peace comes opportunity. ... Eco tourism will bring more jobs to Angola in the future than its oil and gas industries." This sentiment echoed his mother's mission, who said in 1997, "If an international ban on mines can be secured it means, looking far ahead, that the world may be a safer place for this generation's grandchildren." And it looks like Harry is continuing that fight.
Once Harry wraps up in Dirico, he'll continue on to Luengue-Luiana National Park where he'll unveil the Queen's Commonwealth Canopy, similar to the dedication he did while he and Meghan were on Fraser Island during their last overseas tour in the South Pacific. He then moves on to Huambo, that same (yet very different) place his mother walked in 1997, where he will receive a cultural welcome. An emotional day for Prince Harry to be sure.
