Left were amply funded by erst-USSR, and Left would not mind getting funds from China as well. China also would not spending some money to instabilize India by funding the left parties in India. The so called left parties are just like any other petty opportunistic political party with by just holding socialistic ideologies for thier branding and practically nothing. In real world, has any state benefited, by any way, through communist ideologies. It is just a dream theory, with too much of it leading to extremism like Maosim, naxal kind. and too little will lead to what is happening in WB & Kerala.
