"We do believe that one must help both refugees and internally displaced persons…. but the problem of this conference is that it touched upon the issue of the refugees in countries such as Lebanon, Turkey, Jordan, and left behind the internally displaced persons, some 6.5 million people," Yakovenko, the head of the Russian mission to London, told RIA Novosti.
The ambassador recalled that Russia had hugely contributed to the effort to provide assistance to the devastated Syrian population, as it has adequately donated to UN-based international organizations and other relevant organizations.
Yakovenko added that the conference participants managed to collect over $14.5 billion to help Syrian refugees.
The Syrian government was not invited to take part in the conference, which, according to Russia, is "unacceptable," as the government legally coordinates humanitarian aid in the country, the ambassador said.
Syria has been in a state of civil war for almost five years, with government forces fighting against the so-called moderate opposition, a well as jihadist groups.
The internal conflict, instability and humanitarian crisis in the country have forced millions of Syrians to flee their home, becoming either internally displaced or asylum seekers searching for refuge abroad.
