Tibet card is a lost card, whoever plays that card will be at the losing end. China is becoming more powerful each day in terms of economy, military, and technology. They are becoming the big brother of Asia region. The next one will be India.
I don't think India wants to go against China, it will be damaging to their economy. It will be wiser to work with China so it is a win-win situation for both. I personally think they should establish a better relationship to strengthen Asia's position. Historically, Asians are seen lower than the west and the west have taken a lot of advantage on us, it is time we work together to defend our right and pride.
The Tibetans leadership is pro-western countries, they are supported financially by the west. For their own interest, they will jeopardise Asia. For the past 60 years, all they do is condemning how bad China is. So why does India still want to support the Tibetans? India has helped the Tibetans so much but there is no gratitude shown, it is not worthy to help the Tibetans anymore.
