"The summit has become unforgettable not only because of Naadam festival (traditional Mongolian festival), but also because of the dramatic events in the last two says. Both are strong reminder of importance of dialogue and cooperation," Tusk said.
He added that the attempted coup in Turkey may have profound influence on the situation in the region and the country's relations with the EU, but Europe hopes to keep Ankara as a key partner.
"Military coup has no place in Turkey. Disputes cannot be solved with guns. Events continue to unfold, and the situation is still far from stabilization," Tusk said adding that the "key question is what Turkey will come out of this crisis. Consequences will be crucial for the region and for the relations with the EU. Our hope is to keep Turkey as a key partner in all dimensions."
The summit has addressed the issue of cooperation in the security sphere in relation to the situation in Ukraine, the North Korean nuclear program and the South China Sea dispute, Tusk underscored.
"I hope the summit created a positive momentum to finding an agreement on the South China Sea issue. Still, it is not so easy to agree with our Chinese partners on this issue. But these talks are promising," he said.
"We also addressed the global challenge of migration. Strengthening security cooperation has also been central. Ukraine, North Korea and South China Sea have been discussed," Tusk added.
Earlier, it was reported that the Asia-Europe Meeting (ASEM) summit successfully concluded in the Mongolian capital and two final documents were adopted.
