Fáilte Ireland says it is committed to promoting the Northern Sound region as part of "Ireland's Ancient East".
The tourism board had been criticised for continuing to include the county in a brand that covers coastal counties in the south of Ireland.
The "Ireland's Ancient East" brand covers 15 counties, and spreads from Louth as far as Cork City, and as far inland as parts of Offaly and Westmeath.
Sinn Fein's Sean Conlon says Monaghan is 'out of sync' with the other areas within the same branding.
He had sought either moving the county to the "Hidden Heartlands" brand alongside Cavan, or a regional masterplan to connect with other heritage sites in south Ulster.
Fáilte Ireland maintains Monaghan is a "core part" of the current brand, and has its own "distinct and unique tourism, cultural and heritage offerings."
In a statement to Northern Sound News, a spokesperson said investment in the Patrick Kavanagh Centre and Monaghan town, as well as focused workshops such as "Selling South Monaghan" are part of the strategy to increase tourism numbers when restrictions allow.
It added that Monaghan is a "growth market" compared to the likes of Waterford and Wexford, but Fáilte Ireland is working with industry stakeholders to "develop the unique tourism proposition in County Monaghan".
