Haan has been in the post for only six months
Dutchman Arie Haan has told the BBC that he has quit as the coach of Cameroon's national team.
The 50-year-old says he resigned less than six months into a two-year contract because of interference from the president of Cameroon Football Federation Mohammed Iya.
"I am no longer in the position to build a good team for Cameroon because of the interference in my job," Haan told the BBC on Friday.
"Everybody at the federation is interfering especially the president, therefore there is no need for me to stay on.
The Dutchman was unhappy about next Wednesday's friendly against Togo, which he said was organised without his knowledge.
"They did not respect my wishes for the friendly against Togo as all the preparations were done without my approval," Haan said.
"I should be organising the matches for the national team not the federation.
Haan was also furious over his exclusion from the central African country's delegation for the African Youth Championship in Congo.
"I wanted to go to the Africa under-20 tournament in Congo to monitor some of the young players for the national team but they refused.
"This shows that the federation has a different vision from the vision I have for Cameroon football.
Despite his resignation, the Dutchman says he could return to coach the Indomitable Lions if the administration of the game in the country improves.
"I will go back if they change their ways of doing things. My resignation should be a sign to them that if they change their ways Cameroon football will grow."
A star in the Johan Cruyff-inspired Dutch teams of the 1970s, Haan took charge of the Indomitable Lions in August and led them to African Nations Cup qualifying victories over Rwanda and Equatorial Guinea.
However, a football federation official accused him of being absent without leave during December while the Dutchman said he was in Vietnam observing the Cameroon Olympic squad.
