The World Anti-Doping Agency (WADA) has referred Kenya to an ‘independent compliance process’ over the country's record on drug-testing.
Over 40 Kenyan athletes have tested positive for banned substances in the last five years.
Two of them, Joy Sakari and Francisca Koki Manunga, claimed in a media report on Wednesday they were asked for a payment of €14,500 by an Athletics Kenya official for a reduction of their four-year sanctions.
Kenyan officials insist work on a national anti-doping organisation is progressing - but more will have to be done to satisfy WADA.
A statement from the organisation on Thursday evening read: "Concerning media reports regarding Kenya's compliance with the World Anti-Doping Code, WADA confirms that while some progress has been made with the Anti-Doping Agency of Kenya (ADAK), there is still a lot of work required.
"WADA had asked a series of questions to the Kenyan authorities, and stressed that we needed the Kenyan Government to expedite, and show commitment to, the national anti-doping organisation's development.
"We are awaiting concrete plans from the Kenyan Government for the funding of the NADO, and, crucially, the finalisation of Kenya's legislation and anti-doping rules.
"We have not yet received the details nor the assurances we need from Kenya and, therefore, this is now a matter for our independent compliance process."
Russia is currently banned from international competition after being ruled to be non-compliant with the WADA Code.
In addition, IAAF marketing consultant Papa Massata Diack - the son of former president Lamine Diack - former Russian athletics federation (ARAF) president and IAAF treasurer Valentin Balakhnichev and Alexei Melnikov, a senior ARAF coach, are serving life bans from athletics.
The IAAF's ethics commission found the trio had blackmailed Russian runner Liliya Shobukhova (above) and made her pay a bribe for a positive drugs test to be covered up - similar to the offences alleged by Sakari and Koki.
"It's a disgrace to the sport and to ourselves as champions." - Asbel Kiprop
The head of Kenya's Olympic Committee, Kip Keino said that there was a commitment to change.
"There is a change in this country. The government is committed. We saw what happened in other countries like Russia and we don't want that,” he said.
"Time is running out, but we are moving."
Kenyan athlete Asbel Kiprop has won the 1500 metres at the last three World Championships and was also awarded Olympic gold at Beijing 2008 after Bahrain's Rashid Ramzi failed a drug test.
"It's a disgrace to the sport and to ourselves as champions,” he said.
"It's a disgrace to a hard-working athlete when an athlete is found to have used performance-enhancing drugs."
