According to Golden Finance, the call between Russian President Putin and US President Trump ended in the early morning of today (March 19) Beijing time. According to a news released by the Kremlin, the leaders of the two countries continued to exchange views in detail and frankly on the situation in Ukraine. Putin thanked Trump for his efforts to achieve the goal of stopping hostilities and stopping casualties. Putin reiterated his principled position of adhering to the peaceful resolution of conflict and expressed his willingness to work with his US partners to carefully study possible ways to resolve conflicts. The mediation programme should be comprehensive, sustainable and long-term, and of course it must also take into account the absolute necessity to eliminate the source of the crisis and the legitimate interests of Russia in the field of security. In response to the 30-day ceasefire initiative proposed by the US, Russia emphasized several key conditions: effective supervision of the entire ceasefire needs to be implemented, and compulsory mobilization in Ukraine and re-arming of the armed forces must be stopped.
