International relations expert, Dr Vladmir Antwi-Danso says the impeachment of embattled former Brazilian President Dilma Rousseff can affect the bilateral relations and aid signed between Ghana and her country.

‘‘There are instances where yea there are negative impacts but very rare. When there’s a change of government and contracts have been entered falsely, then there is need to revisit the agreement,” he noted.

In an interview with 3FM, Dr Vladmir Antwi Danso was however quick to add that under international law, agreements entered must be fulfilled no matter the person in charge, unless an error is detected in the agreement.

Brazil has invested millions of dollars into Ghana’s economy from infrastructure, agriculture, health to education.

“In international law all agreements entered must be continued. There’s continuity unless… so I don’t believe the impeachment of Rouseff is going to change anything regarding our political, economic ties, unless they have a cause to,’’ he said.

She was succeeded by Michel Temer who was her vice. He promised to take tough measures to restore confidence in the economy.

Meanwhile, suspended Dilma Rousseff has vowed to fight her impeachment after the senate voted to put her on trial.

She has been accused of breaking budget laws and lying to voters about the level of the country's deficit during her re-election campaign two years ago.

But she has described the process as fraudulent and a coup.
