Nigeria's Economic and Financial Crimes Commission says two men charged with money laundering were arrested at the airport carrying $5.4 million in cash and both trying to fly to China.

A statement said businessman Ojukwu Nnamdi Rowland was carrying an undeclared $2.9 million in U.S. dollars when he was searched at the international airport in Lagos, Nigeria's commercial hub, on Oct. 8.

The same day, Ngene Linus Chibuike was arrested carrying $2.5 million. Both men had tickets to fly to China via Ethiopia's capital, Addis Ababa.

The commission said the two were charged at the Federal High Court in Lagos on Thursday and both pleaded innocent and were granted bail.

President Muhammadu Buhari has promised to halt endemic corruption and asked other countries to help return billions of looted dollars.
