Under President Donald Trump's leadership, the United States has withdrawn from international negotiations and commitments, particularly around climate. But the U.S. is very much involved in treaty talks for a global accord to end plastic pollution.

Nations kicked off a meeting Tuesday in Geneva to try to complete a landmark treaty over 10 days to end the spiraling plastic pollution crisis. The biggest issue is whether the treaty should impose caps on producing new plastic, or focus instead on things like better design, recycling and reuse. About 3,700 people are taking part in the talks, representing 184 countries and more than 600 organizations.

Firefighters and local authorities remained on high alert Friday after France's largest wildfire in decades was contained in the south of the country, amid forecasts of very high temperatures which could reignite the blaze.

Over three days, the fire spread across more than 160 square kilometers (62 square miles) in the Aude wine region and claimed one life, forcing hundreds of residents to flee their homes.

At least 10 people died and 33 were missing after flash foods in Yuzhong County in China's northwestern Gansu province, Chinese state media reported Friday.

Heavy rains since Thursday had triggered flash floods and at least one landslide in mountainous areas near the city of Lanzhou, according to state broadcaster CCTV.

U.S. President Donald Trump said Thursday that he would meet with Vladimir Putin even if the Russian leader will not meet with Ukrainian counterpart Volodymyr Zelensky, in comments that suggested Washington and Moscow could soon hold a summit.

Trump's comments followed a statement from Putin earlier in the day that he hoped to meet with Trump next week, possibly in the United Arab Emirates. But the White House was still working through the details of any potential meetings, press secretary Karoline Leavitt said.

Millions of Americans saving for retirement through 401(k) accounts could have the option of putting their money in higher-risk private equity and cryptocurrency investments, according to an executive order signed Thursday by President Donald Trump that could give those financial players long-sought access to a pool of funds worth trillions.

There is no immediate change in how people invest part of their work earnings. Federal agencies would need to rewrite rules and regulations to allow the expanded choices, and that would take months or more to complete. But once done, employers could offer a broader array of mutual funds and investments to workers, according to the White House. New plans could invest in alternative assets, particularly private equity, cryptocurrencies and real estate.

Japanese warships docked in New Zealand 's capital Friday for the first time in almost 90 years amid efforts by Tokyo to deepen its strategic ties in the South Pacific Ocean.

Two destroyers with more than 500 crew on board sailed into Wellington harbor accompanied by the New Zealand navy ship HMNZS Canterbury. The JS Ise and destroyer JS Suzunami were on an Indo-Pacific deployment and arrived from Sydney, where Japan's military took part this month in war games involving New Zealand, Australia and other countries.

Ukrainian soldiers on the battlefield expressed little hope for a diplomatic solution to the war with Russia, as U.S. President Donald Trump's Friday deadline for the Kremlin to stop the killing arrived and he eyed a possible summit meeting with Russian President Vladimir Putin to discuss the conflict.

Trump's efforts to pressure Putin have so far delivered no progress. Russia's bigger army is slowly advancing deeper into Ukraine at great cost in troops and armor while it relentlessly bombards Ukrainian cities. Russia and Ukraine are far apart on their terms for peace.
