But now the resident of the new city project named Kilamba Kiaxi, located some 30 km south of Angola＇s capital Luanda. is enjoying the peace and order of a well-planned satellite city. ＂With complete infrastructure and public utilities, there is not much worry about electricity or water [supply dis- ruptions] that often happen in downtown Luanda,＂ he told ChinAfrica. There are no congestions and Alexandre also has the convenience of sending his children to schools in the city.展开更多
