If China wants to do much in the 21st century, it should never work only on the general skills of international competition and interaction. It is more important to recognize the evolution and development of the world's political characteristics in a timely manner, thereby inspiring a larger Strategic wisdom, keen insight into possible future trends in the world, timely elimination of its own disadvantages that are not suitable for future development, safeguarding the security and interests of the country, and seeking the comprehensive development of society. In other words, the mission of international strategy is not and cannot be for the world. Design some sort of self-righteous ending. What does this passage mean? ["China's international strategy should recognize the evolution and development trend of world political characteristics.", "China's international strategy should eliminate disadvantages that are not suitable for future development.", "China's international strategy should safeguard national security and interests and seek comprehensive development.", "China's international strategy should adapt to the evolution and development of world political characteristics."]
