  The coverage of the Russian invasion of Ukraine has varied widely between
Western, Russian, and Chinese media ecosystems with propaganda, disinformation,
and narrative spins present in all three. By utilizing the normalized pointwise
mutual information metric, differential sentiment analysis, word2vec models,
and partially labeled Dirichlet allocation, we present a quantitative analysis
of the differences in coverage amongst these three news ecosystems. We find
that while the Western press outlets have focused on the military and
humanitarian aspects of the war, Russian media have focused on the purported
justifications for the "special military operation" such as the presence in
Ukraine of "bio-weapons" and "neo-nazis", and Chinese news media have
concentrated on the conflict's diplomatic and economic consequences. Detecting
the presence of several Russian disinformation narratives in the articles of
several Chinese outlets, we finally measure the degree to which Russian media
has influenced Chinese coverage across Chinese outlets' news articles, Weibo
accounts, and Twitter accounts. Our analysis indicates that since the Russian
invasion of Ukraine, Chinese state media outlets have increasingly cited
Russian outlets as news sources and spread Russian disinformation narratives.
