East African Federation potential accession of South Sudan to the EAC may affect the timeline for federation or the scope thereof, but given the infrastructure problems that persist in the fledgling country since President Salva Kiir Mayardit cut off oil commerce with Sudan, the South has decided to invest in constructing pipelines that circumvent Sudan's, which it had been using until that time. These new pipelines would extend through Ethiopia to the ports of Djibouti, as well as to the southeast to the coast of Kenya. These collaborations could increase the likelihood of South Sudan joining the East African Federation at some point.
Equator 84 (World Geodetic System 1984) which is a standard for use in cartography, geodesy, and satellite navigation including GPS, also has an equatorial radius of 6,378.137 kilometres (3,963.191 mi). For both GRS 80 and WGS 84, this results in a length for the Equator of 40,075.0167 km (24,901.4609 mi). The geographical mile is defined as one arc-minute of the Equator, so it has different values depending on which radius is assumed. For example, by WSG-84, the distance is , while by IAU-2000, it is . This is a difference of less than over the total distance (approximately ). The earth
