US President Barrack Obama said that he is not in favor of revoking trade relationship with China, a demand made by several US lawmakers after a row with Beijing over weapons sale to Taiwan. Relations have also been strained by reports of Chinese cyber attacks on US-run websites and a planned visit to the US by the Dalai Lama.In the past few days China has said that it intends to slap sanctions on American companies following Washington's decision to sell arms to Taiwan, prompting Senators from his party to demand revoking trade ties with the Communist nation. Obama said, the US future is going to be tied up with its ability to sell products all around the world, and China is going to be one of the biggest markets. The President said, he will be much tougher with Beijing to make sure it opens its markets to trade with the United States.
