Hangzhou, China (AP) -- The Latest on G-20 summit in China (all times local):
World leaders from 20 industrial and emerging-market nations are arriving in the southern Chinese city of Hangzhou for a summit starting Sunday.
Among the latest arrivals Saturday morning are Canadian Prime Minister Justin Trudeau, who has already visited Beijing and Shanghai on a state visit, and U.N. Secretary-General Ban Ki-moon.
They join heads of state who arrived a day earlier, including Singaporean Prime Minister Lee Hsien Loong, Indonesian President Joko "Jokowi" Widodo and South Africa's President Jacob Zuma — the only African member of the G-20. Argentine President Mauricio Macri and Turkish President Recep Tayyip Erdogan also arrived in Hangzhou.
President Barack Obama is expected to meet later Saturday with his Chinese host, President Xi Jinping. Ahead of the talks, China announced on Saturday that it has ratified the emissions-cutting agreement reached last year in Paris, giving a big boost to efforts to bring the accord into effect by the end of this year.
The United States is also expected to announce that it is formally joining the Paris Agreement.
