The Clinton Foundation has dropped its self-imposed ban on collecting funds from foreign governments and is winning contributions at an accelerating rate, raising ethical questions as Hillary Clinton ramps up her expected bid for the presidency.

Recent donors include the United Arab Emirates, Saudi Arabia, Oman, Australia, Germany and a Canadian government agency promoting the Keystone XL pipeline. . . .

United Arab Emirates, a first-time donor, gave between $1 million and $5 million in 2014, and the German government—which also hadn’t previously given—contributed between $100,000 and $250,000.

A previous donor, the Kingdom of Saudi Arabia, has given between $10 million and $25 million since the foundation was created in 1999. Part of that came in 2014, although the database doesn’t specify how much.

The Australian government has given between $5 million and $10 million, at least part of which came in 2014. It also gave in 2013, when its donations fell in the same range.

Qatar’s government committee preparing for the 2022 soccer World Cup gave between $250,000 and $500,000 in 2014. Qatar’s government had previously donated between $1 million and $5 million.

Oman, which had made a donation previously, gave an undisclosed amount in 2014. Over time, Oman has given the foundation between $1 million and $5 million. Prior to last year, its donations fell in the same range.
