A right wing nationalist movement of the past that supported a monarchy

You have no clue what you’re talking about. The monarchy was already leading, and the movement was aimed at combating the brutal imperialist exploitation of China, so was objectively progressive. Nationalism can be both a good (progressive) and bad (regressive) thing depending on the situation (development of the nation, relationship with other countries, etc.). Using right-wing in this sense is strange, because we could argue numerous historically progressive movements were “right wing” by today’s standards, it means nothing.
