U.S. President Barrack Obama and Turkey President Tayyip Erdogan, two world leader with opposing views on Syrian war, will meet at the G20 Summit in China next month.

The G20 Summit will likely go beyond the conventional approach as both heads intend to plug the cracks of their political relations.

With no end in sight for the Syrian war, the complexity of neutralizing the Al-Assad regime will continue to test the resolve of the two powerful world leaders.

According to Deputy National Security Advisor Ben Rhodes, Obama wants to discuss the circumstances that happened after the failed coup in Ankara last July.

Rhode said the U.S. leader will also present clarifications on the military campaign against the Islamic State (IS) and how to introduce constancy in Damascus.

Turkey's drive into northern Syria did not sit well with Washington as the region is controlled by the Syrian Democratic Forces (SDF), which the Obama administration supports.

On the other hand, Erdogan will request for the extradition of a US-based Turkish cleric named Fethullah Gulen, who has been accused of masterminding the coup. But Washington sought evidence for the supposed participation.

In recent weeks, the Turkish military has moved south to engage with Kurdish Forces. In addition to backing the latter, the U.S. is not keen in accommodating thee option considering that the move will only complicate the anti-Islamic State campaign. 

Secretary of Defense Ash Carter warned Turkey against advancing further south of the Syrian City of Jarablus. 

While an obvious friction between both sides is already in the open, the U.S. approved the liberation of Jarablus and other proximal lands to the west.

Carter has also noted that Washington requested the Kurds to pull-out their units east of Euphrates.

Obama's anticipated meeting with Erdogan is just one of the high-level sit downs with Turkish officials after the visit of U.S. Vice President Joe Biden in Turkey last week.
