Nigeria and Singapore have concluded plans to sign agreements to strengthen their bilateral air services and curb double taxation on investments in both countries.

The Nigeria's ambassador to Singapore, Nonye Rajis-Okpara, disclosed the plan in an interview with the News Agency of Nigeria (NAN) on Monday in Abuja.

Rajis-Okpara said the agreement would be sealed on Aug. 4 in Singapore.

She said it would ensure that passenger air carriers from Nigeria and Singapore would have the authority to operate any number of air services between and beyond both countries.

According to her, the double taxation component of the agreement would clarify the taxing rights on different incomes and investments arising from cross border economic activities involving the two nations.

She said the agreements would also encourage reduction or exemption of tax on certain types of income.

"The main barrier in the negotiation of agreement is the concession of mutual privileges. The two countries must be satisfied that the agreement guarantees that both parties are equal beneficiaries.

"However, the absence of a national carrier in Nigeria to reciprocate the agreement is a major problem but that would be taken care of," he said.

"Singapore seeks to promote an environment where enterprises thrive, ideas flourish and innovation prevails.

Rajis-Okpara said that an Investment Promotion and Protection Agreement would also be signed between Nigeria and Singapore.
