&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&lt;b&gt;BASIS OF PRESENTATION AND CONSOLIDATION&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: left"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The accompanying unaudited consolidated financial
statements of the Company and its subsidiaries have been prepared in accordance with the rules and regulations of the Securities
and Exchange Commission (the &amp;#147;SEC&amp;#148;) including the instructions to Form 10-Q and Regulation S-X. Certain information
and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted
in the United States of America (&amp;#147;U.S. GAAP&amp;#148;) have been or omitted from these statements pursuant to such rules and
regulations and, accordingly, they do not include all the information and notes necessary for comprehensive consolidated financial
statements and should be read in conjunction with the Company&amp;#146;s consolidated financial statements and accompanying notes
thereto for the year ended December 31, 2012 filed with the SEC in the Company&amp;#146;s Form 10-K on April 1, 2013.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In the opinion of the management of the Company,
all adjustments, which are of a normal recurring nature, necessary for a fair statement of the results for the three-month period
have been made. Results for the interim periods presented are not necessarily indicative of the results that might be expected
for the entire fiscal year.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The consolidated financial statements include
the accounts of the Company and its wholly-owned subsidiaries based in the PRC, which include America Pine (Beijing), Bio-Tech,
Inc., Arki (Beijing), E-Commerce Technology Corp., and America Arki (Fuxin) Network Management Co. Ltd, and 51% majority ownership
in Beijing Beitun Trading Co., Ltd. As a result of contractual arrangements with Arki Network Service, the Company consolidates
Arki Network Service. All intercompany balances and transactions have been eliminated in consolidation.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;GOING CONCERN &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company incurred a  net loss
of $352,951 for the six months ended June 30, 2013 and had an accumulated deficit of approximately $3.7 million as of June
30, 2013. The Company has a cash balance of $455,176 as of June 30, 2013. In both 2013 and 2012, the Company mainly financed
its operations through borrowings from directors and officers and from a shareholder. Payables to related parties amounted to
$2,532,794 as of June 30, 2013. Payables to shareholder - Caesar Capital Management Ltd. amounted to $94,179 as of June 30,
2013. There are no formal agreements between the Company and the directors and officers. If the Company cannot generate
enough cash flow from its operating activities, it will need to consider other financing methods such as borrowings from
banking institutions or raising additional capital through new equity issuances. There are no assurances that additional
funds will be available when needed from any source or, if available, will be available on terms that are acceptable to us.
The Company plans to continue to control its administrative expenses in the coming years as well as further develop its sales
from its main business.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;RECLASSIFICATIONS &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Certain prior year amounts have been reclassified
to conform to the current period presentation. These reclassifications had no impact on net earnings and financial position.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;USE OF ESTIMATES &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The preparation of consolidated financial
statements in conformity with accounting principles generally accepted in the United States of America (&amp;#8220;GAAP&amp;#8221;) requires
our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;FOREIGN CURRENCY TRANSLATION &lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#146;s reporting currency is the
U.S. dollar. The Company&amp;#146;s functional currency is the local currency in the PRC, the Chinese Yuan (RMB). The financial statements
of the Company are translated into United States dollars in accordance with ASC 830, FOREIGN CURRENCY MATTERS, using year-end rates
of exchange for assets and liabilities, and average rates of exchange for the period for revenues, costs, and expenses and historical
rates for equity. Translation adjustments resulting from the process of translating the local currency financial statements into
U.S. dollars are included in determining comprehensive income.&amp;#160;As of June 30, 2013 and December 31, 2012, the cumulative translation
adjustment of $71,824 and $73,342, respectively, was classified as an item accumulated of other comprehensive income in the stockholders&amp;#146;
equity (deficit) section of the consolidated balance sheets. For the six months ended June 30, 2013 and 2012, the foreign currency
translation adjustment to accumulated other comprehensive income (loss) were $(1,518) and $(9,078), respectively. For the three
months ended June 30, 2013 and 2012, the foreign currency translation adjustment to accumulated other comprehensive income (loss)
were $(2,313) and $(1,371), respectively.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accounting Standards Codification (&amp;#147;ASC&amp;#148;)
Topic 820 requires the disclosure of the estimated fair value of financial instruments including those financial instruments for
which fair value option was not elected. As of June 30, 2013 and December 31, 2012, the carrying amounts of the Company&amp;#146;s
financial assets and liabilities approximated their fair values due to short maturities or the applicable interest rates approximated
the current market rates.&lt;/p&gt;
