United States Geo-strategy in Asia Pacific; Change or Continuation?

Introduction Asia pacific is an important region in world economy and security. Given to this, and because of growing power of china and increased threat of North Korea, U.S. in recent years has concentrated to this region. It's clear manifestation was Asia pivot or rebalancing by Obama's administration. But, Donald Trump as elected U.S. new president both in his election campaign and after winning the completion, has declared some new principles that are very different from past. Because of this, in this article, we are seeking the answer to these question: is there a new trend in U.S. in relation to Asia Pacific? Do the geostrategic pivot of Washington in changing?
Methodology With a descriptive-analytical method, present work try to analyze the limitation and requirements of U.S. Foreign Policy in contemporary era.
Findings The significances of Asia pacific for U.S. are:- Presence of U.S. allies in this region;
- Growing region Economic contribution in world economy;
- China's rising;
- North Korea threat;
- Taiwan issue;
- South and east China sea.
American Asia Pivot strategy: Asia pivot is the strategy the U.S. under Obama specially from 2011 has pursued. The pillars of this strategy are:- Promotion of U.S. alliance system and increase the relations with rising partners
- Enforcing institutional and multilateral presence
- Enhancing military activity in the region
- Trying to promoting the human rights situation in regional countries
The limitations and opportunities of U.S. declared policy by Trump in Asia Pacific region: Donald Trump has declared some promises that some of them are impossible because of their costs for American position in international system and its economy and welfare of people. These declared policies by Trump include: increasing tariffs on imported goods from China to U.S.; decreasing Washington support of allies; exit from some institutional framework such as TPP and … .
This study for analyzing this issue has focused on behavioral requirements of a pole in unipolar system. For keeping the status quo, U.S. as the only pole in international system should maintains its alliances with regional power to balance against a growing power. In addition to this, increasing tariff against Chinese goods causes retaliation from china. This, also can increase the prices of goods in U.S.. Moreover, retreating from T.P.P leads to increase in China's regional and institutional role. It should be noted that contrary to Trump naive view, American companies have gone to china because of cheap labors costs, as a result they don’t prefer to come back to U.S. even, they prefer to go to cheaper countries such as Vietnam. Analysis Given to this situation and existence a systemic approach in U.S. establishment on grand strategy of white house, it seems that Washington maintains its alliances in Asia Pacific, keeps its military presence, and as same as past, U.S. will prefer to continue its relations with China, so their relation have both elements of conflict and cooperation. In addition, Trump administration probably continue American Taiwan past policy, and we don’t see any break from conventional policy.
Conclusion It seems that the U.S. under Trump will follow the major of rules that may maintain their country as the salience power in international system. Even if he want to basically change its foreign policy, the establishment oppose to his approach. Keeping the status quo, trying to maintain unipolar System that U.S. is its leader, has some requirements that American leaders know it well.
