The decree, issued late Thursday, is similar to an executive order, but is ambiguous about what happens to those who don't comply. It also does not spell out who will pay for the government cleansing that Karzai proposed.
Political analyst Jawid Kohistani said he did not think the decree would stave off corruption in the government.
"Karzai is acting late on corruption," he said Friday. "We have anti-corruption laws, but it is very difficult to remove corruption. It is hard to just remove corruption by a decree. He should start to remove corruption from inside the palace.
"I'm not confident that this decree will bring good results because those people who are involved in corruption are high-ranking officials in the government.
