Laos in the 1970s and 80s basically followed Vietnam's lead in everything, since China and the USA worked together to try and foment anti-communist rebellions in the country. In the early 90s it expanded relations with the West and nowadays gravitates between Vietnam, China and the USA.
Its economic, cultural, etc. policies are to the right of those in Vietnam, in part because Laos is a lot poorer and in part because Marxism-Leninism as an ideology is pretty much totally ignored (whereas in Vietnam and China it is hypocritically "upheld," in Laos Buddhism is basically all anyone ever talks about, even government/party officials.)
I don't know what the position of the Laotian party on Stalin is, but in China, Vietnam and the DPRK he is still nominally upheld alongside Marx, Engels and Lenin (whereas the Cubans continue to uphold the post-1956 Soviet revisionist assessment.)
The Laotian national liberation struggle was assisted by the USSR and China in the 1950s-70s but got the bulk of its ideological and military guidance from the Vietnamese. The Laotians followed the Vietnamese policy during those years of trying to be on the good side of both the Soviet and the Chinese governments.
