G20 Summit Live Updates: Trump Seems to Make Joke of Russia’s Election Meddling

It was a clear reference to the huge protests in the city over a proposed law that would allow extraditions to mainland China. Mr. Abe also “emphasized the importance of upholding international values such as respect of freedom and human rights,” including with the Uighurs, ethnic minorities whom China has been persecuting by putting them in indoctrination camps.

The agenda includes trade, women and climate change.

During the two-day gathering of leaders from the Group of 20, the meeting’s official themes will include global economic risks, trade disputes, job growth and investment, innovation and artificial intelligence, and women in the workplace.

Several countries are also hoping to emphasize collective action against climate change, which could become a point of contention. Japan is emphasizing the problem of plastic litter in the world’s oceans and seas, and President Emmanuel Macron of France, in a direct challenge to President Trump, has threatened not to sign any official joint statement out of the meeting that does not include an affirmation of the 2015 Paris climate agreement.

But Mr. Trump has called climate change a hoax, disputed its causes and vowed to withdraw the United States from the agreement.

In the hours before and after leaving for the summit, Mr. Trump lashed out at three nations whose leaders are attending — Germany, India and the host, Japan. He is scheduled to meet with those countries’ leaders on Friday.

The Group of 20, which is meeting in Osaka, Japan, this year, is an organization of finance ministers and central bank governors from 19 countries and the European Union. In addition to the United States and the bloc, its members include China, Japan, Germany, France, India, Brazil, Mexico, Canada, Saudi Arabia, Britain, South Korea, Turkey, Italy, Russia, South Africa, Indonesia, Argentina and Australia.
