I looked this up at the top English language source for information on the Chinese military,
http://www.sinodefence.com/ . They don't have any information about small arms anymore for some reason so I used the wayback machine at
http://www.archive.org/web/web.php to view their archives. The Type 69 page refers to it as "Type 69 rocket launcher". The phrase "rocket propelled grenade" is used to describe the ammunition, though they are not type classified as such, instead using names like "Type 69 HEAT", "Type 69-1 HEAT", etc. Additionally, the photographs of the ammunition have labels describing them as "rocket shells". These labels are part of the photographs and are not text captions, indicating that where ever they originated from used that phrase to describe them.
