ISLAMABAD (Agencies) - China has assured full moral, financial and material support to Pakistan in the wake of the situation that has arisen after terrorist attacks in Mumbai. China in a message to Pakistan's top slot said that the country would assist Pakistan in any situation to overcome the problems and challenges being faced by it. The Chinese leadership is in constant contact with Pakistan to know the nature of assistance the latter requires and ensure its immediate availability. However, according to official sources, Pakistan is self-sufficient in defence and it is impossible for any state of the world to harm the country. They said Pakistan Army, Navy and Air Force were well equipped to protect the homeland. Meanwhile, EU foreign policy chief Javier Solana on Monday urged Pakistan to help Indian authorities investigate the terrorist attacks in Mumbai. Solana spoke by phone Monday with both Pakistani Foreign Minister Shah Mehmood Qureshi and his Indian counterpart Pranab Mukherjee following the devastating militant attacks in Mumbai which left at least 172 dead and close to 300 wounded. In his call to Qureshi, Solana "encouraged the Pakistani government to pursue the fight against extremism and terrorism." Without accusing Pakistan of involvement, he also urged Islamabad "to support the Indian authorities in the investigation on the terrorist attacks."
