China, unlike Russia, engages in soft power. It uses the means of subversion and slow coercion to slowly extend its influence and strengthen its position. It doesn't invade countries or sends mercs/pmc's like Russia does (though they do have their online paid troll farms), China does it more in an economic sense.
However, it is no different than what Russia does. It is trying to expand at the expense of others. It is extremely nationalistic and authoritarian/dictatorial. It must be checked like any other aggressive country.
