Does the leader of Hong Kong appear weaker withdrawing the extradition bill?

Well as we'd say in Australia, "Is the Pope a Catholic?" Of course. This means that Carrie Lam's authority within the Hong Kong SAR is reduced and her standing in Beijing is reduced as well. But I think the bottom line is that China will resist any efforts to remove her from office, despite local pressure.

Is the US – China trade war coming to an end anytime soon?

Depends Dr. Bremmer on what your definition of "any time soon" happens to be. My prediction is simply this: once they get to the G20 meeting in Osaka Xi Jinping and President Trump will agree to reboot the negotiations process but then it's a question of the substance of the deal. My prediction is A) there will be a deal sometime between now and the end of the year. And secondly, the nature of the deal will be America yielding on the questions of tariffs to the Chinese and China yielding to the Americans on the amount that President Trump expects in the purchasing order of future American goods by the Chinese. That's my bottom line. Both countries need the economic outcome. Both countries therefore have a deep interest in securing a deal. Doesn't mean the end of the economic war however, technology reigns supreme.
