Twin Oaks (Chinese: 雙橡園; pinyin: Shuāng Xiàng Yuán) is a 17-acre estate located in the Cleveland Park neighborhood in Washington, D.C., United States.

The historic residence, completed in 1888, was designed by Francis Allen for Gardiner Greene Hubbard, a founder and first president of the National Geographic Society and father-in-law of Alexander Graham Bell, the inventor of telephones.

The ceremony was held by the Taipei Economic and Cultural Representative Office in the U.S., a move symbolizing significant progress in Taiwan–United States relations.

We remain fully committed to the U.S. One China Policy, based on the Three Communiqués and the Taiwan Relations Act.
