Hong Kong's end? Last month we mulled the question: is Hong Kong as we know it over? As of yesterday, the answer is: yes. China has now implemented a new national security law for the city, which criminalizes secession and collusion with foreign forces. The law in effect ends the autonomy granted (by international agreement) to Hong Kong when it reverted from British control to Chinese rule in 1997. Critics fear it will be used to stamp out the remnants of the pro-democracy protests that erupted last year in response to a separate attempt by Beijing to expand its writ over the city. We're watching to see what the city's fearless but increasingly encircled protesters do now. And we're also eyeing the reaction from abroad. Washington has begun rescinding Hong Kong's special trade and investment privileges, and will now treat the city the way it treats the rest of China. The move is meant to punish Beijing, but unlike twenty years ago when Hong Kong accounted for a fifth of China's economy, today it's less than four percent. Those who suffer most may be Hong Kongers themselves.
