+# huaweicloud_rms_resource_tags
+
+Use this data source to get the list of RMS resource tags.
+
+## Example Usage
+
+```hcl
+variable "resource_type" {}
+
+data "huaweicloud_rms_resource_tags" "test" {
+  resource_type = var.resource_type
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+* `resource_type` - (Required, String) Specifies the resource type.
+  The valid value can be **config:policyAssignments**.
+
+* `resource_id` - (Optional, String) Specifies the resource ID.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `tags` - The tags.
+
+  The [tags](#tags_struct) structure is documented below.
+
+<a name="tags_struct"></a>
+The `tags` block supports:
+
+* `key` - The tag key.
+
+* `values` - The tag values.
