Generally speaking, economically developed countries should bear more responsibilities. But neither economy can shirk its responsibility, and both should shoulder the responsibility commensurate with national strength. This requires western developed countries to bear more responsibilities on this issue, while relatively backward developing countries bear less responsibilities. However, they should all do their part. The United States is the world's largest power, and its responsibility is of course very important, so the United States should not turn its domestic crisis to other countries; Compared with China, we have a great responsibility, because China is the third largest economy in the world, and its impact on the world economy is no less than half that of the United States. Therefore, China should better assume its responsibility as a responsible big country, and there must be no falsehood, otherwise it will plunge the already collapsed economy into a deeper abyss.
