40-year-old Monk Lorang Konchok was sentenced to death with a two-year reprieve and has been stripped of his political rights for life, in what was seen as a deterrent punishment in the region hit by unrest.
His nephew, Lorang Tsering, 31, was sentenced to 10 years in prison and has been stripped of his political rights for three years, state-run Xinhua news agency quoted the court verdict as saying.
The two incited and coerced eight people to self- immolate, resulting in three deaths, the Intermediate People's Court of the Tibetan-Qiang Autonomous Prefecture of Aba found.
Also a county court in Gannan Tibetan Autonomous Prefecture of northwest China's Gansu Province sentenced six ethnic Tibetans to three to 12 years in prison for their roles in a local villager's self-immolation in October, according to the report.
Asked whether the stiff sentences were aimed curbing self immolations, Chinese Foreign Ministry spokesperson Hong Lei told media that "it is clear from the cases that Dalai Clique is plotting and inciting the self-immolations."
"Relevant personnel incited and abetted others to self-immolate in order to cooperate with the Dalai Clique's political schemes of splitting China," he said.
Such behaviour violates Chinese laws and the people who were sentenced pleaded guilty, Hong said adding that through the trial of cases, the international community can "condemn the ugly behaviour of the Dalai Clique in inciting and abetting self-immolations" .
Monk Konchok was accused by the prosecutors of receiving instructions from fellow Monks settled in Dharmashala and incited the immolations calling for return of the Dalai Lama from self exile. His confessions were widely telecast in China.
About 95 people set themselves on fire in the recent months in different part of Tibet Autonomous Region and Tibetan prefectures, which China blamed it on the Dalai Lama and his supporters to discredit the Chinese government.
Konchok is the second Monk to have been convicted.
Monk Drongdru was sentenced to 11 years in 2011 at the same place for plotting, instigating and assisting the self immolation of fellow monk.
Last month China has brought a new law in Tibet making inciting others to set themselves on fire or not affectively intervening to stop people indulging in such acts as an "intentional homicide".
According to the new regulation people who plan, organise, incite or help others to perform self-immolations will be tried for intentional homicide.
According to the court Konchok, a monk in Aba's Kirti Monastery, maintained long-term and close contact with Samtan, a member of an overseas "Kirti Monastery media liaison team" -- a "Tibet independence" organisation.
He used his status as a "geshe," or a high-level Tibetan religious scholar, to convince monks and others to self-immolate, the court said.
Konchok sent information regarding self-immolations to Samtan.
The information was used by some overseas media as a basis for creating secessionist propaganda, according to the court.
The two convinced eight people to self-immolate, constituting the crime of intentional homicide, the verdict said.
Konchok was described by the court as the prime culprit, which would typically result in a death sentence.
After he was arrested, Konchok recounted the main facts of the case, pled guilty and showed repentance during the trial, which led to his punishment being mitigated, the verdict said.
Lorang Tsering acted under Lorang Konchok's instruction, according to the court, adding that he played a secondary role as an accessory.
He also recounted the main facts of the case, pled guilty and showed repentance during the trial, leading to a lighter sentence, according to the verdict.
More than 130 people were present when the verdict was handed down. They included the relatives and friends of the two defendants, the Xinhua report said.
