Azerbaijan’s Deputy Foreign Minister Elnur Mammadov met on September 8 with David Allen, the U.S. Chargé d’Affaires in Armenia, during Allen’s visit to Baku, according to Azerbaijani reports. U.S. Chargé d’Affaires in Azerbaijan Amy Carlon also attended the meeting.

The talks focused on the Armenia-Azerbaijan so-called “peace process,” regional security, and steps toward a long-term settlement, as well as the implementation of the Trump Route for International Peace and Prosperity (TRIPP).

The sides also discussed infrastructure planned under TRIPP and the establishment of the TRIPP Development Company, which is expected to oversee the project’s development.

TRIPP emerged from the August 8, 2025, Washington summit between Nikol Pashinyan and Azerbaijani President Ilham Aliyev, hosted by U.S. President Donald Trump. The project would establish a transit route through Armenia’s strategically sensitive Syunik region, providing a direct connection between mainland Azerbaijan and Nakhijevan.

Pashinyan’s government has presented the arrangement as a project that preserves Armenian sovereignty, emphasizing that Armenia will retain jurisdiction and responsibility for border, customs, and security functions. Critics, however, have raised concerns over the long-term implications of placing strategically important infrastructure in southern Armenia under a structure in which Armenia would initially hold only a minority stake.

Under the Armenia-U.S. framework, the TRIPP Development Company is planned with a 74% U.S. stake and just a 26% Armenian stake for an initial 49-year period. If the arrangement is extended for another 50 years, Armenia’s share would rise to 49%.

The discussions in Baku further underscore Azerbaijan’s direct involvement in shaping a project located on sovereign Armenian territory and promoted by the Pashinyan government as part of its broader regional “peace” agenda.

Mammadov and Allen also discussed Azerbaijan-U.S. relations and cooperation under the Strategic Partnership Charter signed by Washington and Baku in February 2026.

At the time Azerbaijani reports emerged, there was no corresponding public readout from the U.S. Embassy in Yerevan regarding Allen’s meeting with Azerbaijani officials or the discussions surrounding TRIPP.
