Damage to the Chinese economy can't happen in isolation
When the second largest economy in the world goes on lockdown, it is inevitable that there will be significant global effects.

China is far more integrated into the global economy than it was at the time of the SARS outbreak, and the global economy in general is far more interconnected. Major damage to one of the world's biggest economy cannot simply be shielded from other economies in an era of globalisation. Dramatic declines in commodity prices have had knock-on effects for commodity export dependant markets. Industries from pharmaceuticals to tourism are bracing for impact. The rest of the world avoiding the damage the Chinese economy has suffered is impossible. The Chinese economy is no longer as isolationist as it once was, so knock-on effects to the global economy are inevitable.
[P1] The Chinese economy is heavily integrated into the global economy. [P2] Impact from coronavirus on the global economy is inevitable.
