Others who attended, and spoke at the summit, included Princess Charlene of Monaco and the former president of East Timor, Jose Ramos-Horta.
China views the Dalai Lama as a "splittist" and has repeatedly criticised moves by foreign governments - including India - that it believes provide political legitimacy to the monk.
December 16: China today accused India of disregarding its concerns in hosting the Dalai Lama at Rashtrapati Bhavan last week, warning of a disturbance to ties in a terse protest that highlights the tension between Asia's two largest nations.
China has called the Dalai Lama a "wolf in sheep's clothing" and accused him of fomenting separatism in the Tibet Autonomous Region (TAR) and inciting self-immolations.
Geng indicated the meeting hurt one of China's "core" interests about TAR remaining part of the country. Just recently, India's diplomatic efforts to get China's backing for NSG membership bid and getting JeM chief Masood Azhar banned by the United Nations seemed to have come a cropper with Beijing saying its stand on the two key issues "remains unchanged".
Geng asked India to "fully respect China's core interests and major concerns" and "take effective means to remove the negative impact caused by the incident to avoid any disturbance to China-India relationship".
"China is strongly dissatisfied and resolutely opposed to this", he said, adding that the Dalai Lama used the guise of religion to engage in separatist activities and China opposed any form of official contacts with him.
New Delhi's moves are being perceived as an attempt to gain leverage with Beijing.
Beijing's sharp reaction came after it became known that the Dalai Lama could visit Arunachal Pradesh in early 2017 at the invitation of the state's chief minister Pema Khandu.
"The Dalai Lama is a political refugee who has always been engaged in activities to split China and alienate Tibet from China in the name of religion". Mongolia's crisis followed its reception of Dalai Lama last month, apparently triggered a slew of economic measures by Beijing against Ulan Bator.
