KIGALI, Feb. 23 (Xinhua) -- Rwanda maintained the third position in the fight against corruption in Africa and is ranked first in East Africa, according to Corruption Perception Index 2017 released by Transparency International on Thursday.

Among 180 countries, Rwanda was ranked 48th least corrupt country globally, up from 50th place in 2016, said the report released in Rwandan capital Kigali. Tanzania moved from 106th in 2016 to 103rd place in 2017, said the report.

Uganda maintained 151th position as in 2016 while Burundi is ranked 157th after improving two places compared to the previous year.

Kenya dropped two places to number 143, it said.

Botswana emerged first in Africa, ranked 34th globally, while Seychelles is the second in Africa and 36th in globally, report showed.

Countries need to build functioning institutions to be able to fight graft, said Albert Kavatiri Rwego, program manager at Transparency International Rwanda, when briefing journalists in Kigali.

Rwego said corruption was prevalent in countries ravaged by conflicts and wars.

Some of the strategies Rwanda has employed to fight corruption include offering public tenders through online system, as well as common services that locals seek from leaders which reduce contact, according to Clement Musangabatware, Rwanda's deputy Ombudsman in charge of Preventing and Fighting Corruption.
