India is a democracy, government's got to convince everyone …
India is a federation of ~30 states, with wildly varying levels of democracy. Now this is usually a good thing; it has allowed us to accomodate a great deal of cultural and economic diversity without breaking up. But a major cause of the pollution in Delhi is stubble burning in neighbouring, which the government of Delhi has no power over. And the union (i.e. federal) government is led by a different party, so they don't co-operate with the Delhi government.
Don't be ridiculous, the opinions of the citizens of other countries don't matter! What really matters is how I, the enlightened Westerner feel about it based off of what my country's state media tells me! Chinese people don't know what they really want, which is a new cold war egged on by dangerous hoaxes and sinophobia!
