NEW YORK - The Clinton Foundation will continue to accept funding from foreign governments in the wake of Hillary Clinton's decision to run for the US presidency, but only from six countries that already support it, the charity said on Wednesday.

Clinton, the current favorite to become the Democratic nominee, has said the foundation's charity work is a source of pride, but it has also drawn growing criticism from political opponents and parts of the US media.

Foreigners are not allowed to give money directly to presidential election campaigns, and Clinton's critics say foreign governments and entrepreneurs may instead be donating to her family's charities to curry her favor.

The foundation's board of directors also voted to publish the names of new donors more frequently - four times a year, instead of annually - according to the foundation's statement. Clinton stepped down from the board on Sunday. Her husband, former President Bill Clinton, and their daughter, Chelsea Clinton, remain members.

"While it's common for global charities to receive international support, it's rare to find an organization as transparent as the Clinton Foundation," Craig Minassian, a foundation spokesman, said in a statement.

In order to become secretary of state in 2009, Clinton and her husband signed a similar transparency agreement with Barack Obama's incoming presidential administration in order to defuse questions about conflicts of interest.
