KHARTOUM, Dec. 25 (Xinhua) -- Sudan and Chad have agreed to revive a security protocol to control joint borders and ban any activities by armed opposition groups in the two countries, senior officials of Sudan and Chad said on Friday.

"We have agreed to revive the security protocol through a joint meeting of military and security officials from the two countries, to be held in the Chadian capital of N'djamena in two weeks," Chadian Minister of Foreign Affairs Moussa Faki Mahamat told reporters in Khartoum Friday.

Mahamat stressed his country's seriousness to normalize political ties with Sudan and resolve all issues of difference.

"We held deep, serious and frank talks in Khartoum. We came here to confirm our real desire to overcome differences and make sure that our brothers in the Sudanese government share this desire, something which we really sensed," he said.

He underscored importance of building trust between the two sides, adding that "we will begin with controlling the borders and banning the opposition activities along the joint borders as it is the core of the conflict, and then we will discuss the other files."

Mahamat further expressed N'djamena's readiness to support the forthcoming Doha-hosted peace talks between Sudanese government and Darfur armed movements.

"We support these talks and we have participated in most of its meetings. If Khartoum asked for any type of support on our part that would achieve positive outcome, we will be there," he said.

The Chadian official did not ruled out the possibility of holding a summit between Sudanese President Omar al-Bashir and his Chadian counterpart Idriss Deby.

"If positive movement is achieved in all files, then it is natural that a summit for the two leaders would be convened to bless what we have achieved," he said.

Sudanese Presidential Adviser Ghazi Salahuddin, for his part, told reporters that the Sudanese government was keen to normalize relations with Chad and remove all obstacles that caused the tension in bilateral ties.

"We honestly desire to improve the relations with Chad. There is no justification for this difference between the two sister countries," said Salahuddin.

He affirmed importance of controlling the joint borders and implementing all protocols signed by the two sides.

"As the conflict represented the hostile activities which were launched across the joint borders, we focused on the implementation of the signed security protocol without the need for new ones," he said.

The Sudanese official denied that foreign intervention would affect the ongoing efforts to normalize the ties between Khartoum and N'djamena.

"It is in the interest of any country that has influence in the region, particularly France, to see the Sudanese-Chadian relations back to normal. War doesn't serve any party," Salahuddin said.

The Chadian foreign minister arrived in Khartoum on Thursday and met the Sudanese president and officials from the Sudanese Ministry of Defense and Security and Intelligence Service.
