The short trajectory of the latest US-DPRK detente has already shown that as long as both parties demonstrate sincerity, previously unimaginable things may happen. Just months back, who would anticipate Pyongyang being so enthusiastic about ending animosity, even willing to negotiate over nuclear weapons, which it had long held as non-negotiable?

It certainly would have been better had Pompeo left Pyongyang with an agreement on a second summit meeting. But once the two leaders do meet again, no matter where, no matter when, they will have to have in place something concrete to deliver. The two parties obviously need more time for that.

The bargaining will be tougher going forward — as one official on Pompeo's team observed, it is likely to be a long haul.

But the detente, and denuclearization, will surely not be materialized with the United Nations sanctions now in place. Pyongyang has just reiterated denuclearization will not happen unilaterally, the ball is in Washington's court.

Two systems still in place despite claims to contrary: China Daily editorial

Ungrounded accusations from some foreign governments over the decision by the Immigration Department of the Hong Kong Special Administrative Region not to renew the work visa of a foreign correspondent in the SAR are the latest attempt to undermine the principle of "one country, two systems" and attack the central and SAR governments.

Although the Hong Kong immigration authority has not given any specific reasons for not renewing the work visa of Victor Mallet, Asia news editor at the Financial Times, it is a usual practice of immigration authorities worldwide not to comment on individual cases, and visa renewal is a sovereign right that no other governments are allowed to interfere in.

Foreign governments demanding an explanation know this. What they really want is not an answer but to create the illusion that freedom of speech and the press in Hong Kong is dwindling.
