Angola's President Jose Eduardo dos Santos has called for a crackdown on government corruption².

安哥拉总统若泽·爱德华多·多斯桑托斯号召对政府腐败进行压制。

Angola's leader is committed to tackling corruption

The president, who has been in power for 30 years, said his country's oil wealth had been squandered⁴（浪费，挥霍） by irresponsible officials.

Mr dos Santos said members of his MPLA party had been "too timid（胆怯的，害羞的）" in their attitude towards government spending.

Last week Angola was named by Transparency International as one of the world's most corrupt¹ nations.

Mr dos Santos said the lack of supervision⁵ over spending had led to fraud and wasted public funds.

In a speech to his party, he said: "Irresponsible people, people of bad faith, have taken advantage of this circumstance to squander³ resources and to carry out illicit⁶（不法的，不正的） and even damaging and fraudulent（欺诈的） acts of management."

He called for further transparency and said good government required a lot more work.

"The thing is to agree to a sort of zero tolerance⁷ after the sixth congress," he said.

The party is due to hold a national congress next month.

Angola is Africa's biggest oil exporter, and investment from China has helped the economy make a remarkable⁸ recovery following decades of civil war.

But according to figures from the World Bank, most of the population lives on less than $2 (£1.2) a day.

Human rights groups have urged Mr dos Santos - who is reported to be one of the richest people in the country - to lead by example. He denies any wrong-doing.
