On 28 June 1991, he became head of the Committee for External Relations of the Mayor's Office, with responsibility for promoting international relations and foreign investments.
Additional fighting took place throughout the day. The YPA tank column that had been attacked at Pesnica the previous day was blocked by impromptu barricades of Slovenian trucks at Štrihovec, a few kilometers short of the border with Austria, where it again came under attack by Slovenian TO personnel and Slovenian police. The SFR Yugoslav Air Force mounted two airstrikes in support of the YPA forces at Strihovec, killing four truck drivers. At Medvedjek in central Slovenia, another YPA tank column came under attack at a truck barricade, where air raids killed six truck drivers. Heavy fighting broke out at Nova Gorica on the border with Italy, where the Slovenian Special Forces fired two armburst antitank rockets and fired 700 rounds from infantry weapons. Slovene troops destroyed two YPA T-55 tanks and captured an additional three, plus a BTS-1 racked buldozer. Three YPA soldiers were killed and 16 wounded, among them the commander of the armored column, and 98 surrendered. By the end of the day, the YPA still held many of its positions but was rapidly losing ground. YPA was beginning to experience problems with desertions — many Slovenian members of the YPA quit their units or simply changed sides - and both the troops on the ground and the leadership in Belgrade appeared to have little idea of what to do next.
