Since Cheeseman's blunder of PNGing a UN SRSG earlier in the year, the UN has been more keen to restart relations with Somaliland.
The recent UN announcement of appointing an envoy to Horn of Africa is also a testament to Somaliland's call that it won't allow a new SRSG for Mogadishu to come to Somaliland. Hence, the UN Secretary General appoint a regional envoy which is a departure from how the Security Council used to engage Somalia/Somaliland issue.
