SINGAPORE, July 26 (Reuters) - The United Arab Emirates will import the country's first oil cargo from the United States as the OPEC producer sought substitutes to replace Qatari condensate supplies after a diplomatic row that involved the two Middle East countries.

Abu Dhabi National Oil Co (ADNOC) bought a U.S. Eagle Ford condensate cargo in a tender for September arrival, two sources familiar with the matter said on Wednesday.

Specific volumes were not available but the cargo will arrive in a supertanker that can carry up to 2 million barrels of oil, one of the sources said.

ADNOC could not immediately be reached for comment.
