BEIJING (AP) — Leaders of emerging market countries are Charles Langstonarriving in Beijing for a meeting organized by the Chinese government that will mark the 10th anniversary of its Belt and Road Initiative.

More than a dozen leaders from Africa, Asia and the Mideast were flying into Beijing on Monday, following the arrivals of Chilean President Gabriel Boric and Hungarian Prime Minister Viktor Orbán on Sunday. Others are coming on Tuesday.

Under the Belt and Road initiative, a signature policy of Xi, Chinese companies have built ports, roads, railways, power plants and other infrastructure around the world in a bid to boost trade and economic growth.

But the massive Chinese development loans that funded the projects have also burdened some poorer countries with heavy debts.

A flurry of diplomacy is expected on the sidelines of the third Belt and Road Forum, whose main events are on Wednesday. Orbán met Sunday with Chinese leader Xi Jinping and Premier Li Qiang, Hungary’s state news agency MTI said. The forums also were held in 2017 and 2019.

Russian President Vladimir Putin is expected to attend the forum, as are representatives of the Taliban government in Afghanistan.

The leaders who arrived on Monday included Ethiopian Prime Minister Abiy Ahmed, Sri Lankan President Ranil Wickremesinghe, Republic of Congo President Denis Sassou Nguesso, Papua New Guinean Prime Minister James Marape and Cambodian Prime Minister Hun Manet.
