The Bharatiya Janata Party slammed Congress over its alleged connections with China and its firms after Supreme Court's observations that how can a political party sign an agreement with a political outfit of a foreign country. "Even the SC is surprised at the MoU signed by the Congress party with the Chinese Gov...Mrs Gandhi & her son, who led the signing, must explain. Does this explain donations to RGF and opening Indian market for the Chinese in return, which affected Indian businesses," BJP president J P Nadda asked in a tweet.
