While US-China relations remain normal with the biggest trade relationship  in the world,there is always an undercurrent of mistrust between the world’s two largest economies.Chinese companies have been repeatedly blocked from acquiring US assets and technology due to Security Concerns.This is quite notable as US does not normally reject any foreign takeovers of its companies.Recently Telecom Equipment Giant Huawei failed in its takeover attempt of an US Technology Asset.This was not the first time that Huawei has been blocked as earlier its buyout attempt of 3Com was summarily dismissed by the US government.One of the main reasons for the concern is that most Large Chinese companies are State Owned with close ties with  the Communist Government.This makes the US lawmakers cagey about Chinese investments.The concerns are only growing stronger as Anshan Steel,the 4th largest Chinese Steel Maker was blocked from investing in US based Steel Development Company.The move was opposed by 50 lawmakers on both sides of the political spectrum ultimately leading Anshan to call off its bid.Note Steel is not a High-Tech Product and the rejection seems to indicate a further level of Chinese mistrust.China has also not been too considerate of US takeover attempts of its companies.The most famous rejection was Coke’s $2.3 Billion Bid for Juice Maker Huiyan.
