Why are Chinese so afraid of Modi?

1. It is not only Chinese so afraid of Modi but also they are jealous of not having such a leader in China or Chinese leaders are not as bold as he is. In spite of so much of verbal provocations from Chinese side, Modi has been keeping calm, and silent, which is perturbing to them. All their psychological warfare is going into the drain putting them in a spot of confusion as to what to do next.
2. China which is having the ambition of becoming the world's superpower has been silencing many smaller nations and island states by its Jingoistic tactics or belligerent attitudes. But in the case of India they have failed. Now their superpower dream is hanging fire. The world is watching them and their moves keenly. They may not be taken seriously in future. Also in a full scale war the result is anybody’s guess. Chinese are wary of full scale war.
3. Modi has in a short span of three years developed India into a powerful country. India has the support of the entire world, except perhaps Pakistan and North Korea. Trump called Modi a friend openly hugging him several times, so also Isreal PM. Indian diplomacy and its reach far out spaced that of China.
4. Modi cannot be bought by enticing him like what they are doing in other smaller island states. Modi’s passion towards the nation and his nationalism is unquestionable. China is worried about their future course of action regarding India.
5. Modi’s firm stand has put the Chinese in a piquant situation. If they withdraw their troupes the world will not respect them. Other smaller nations too may raise against them. If they go for war it will end in destruction and loss of lives. Either way China is going to lose. It's ambition of becoming superpower will be held up or postponed. This is not what they wanted.
