If the united states imports more goods from japan than it exports to japan, how will the difference be financed

If the United States imports more goods from Japan than it exports to Japan, how will the difference be financed? The United States will sell the assets they receive so that Americans who want the product are obligate to pay for future imports of those items. Basically, the United States will make sure Americans are wanting and willing to pay for the items they are importing for us to have from Japan or they will stop important those items. Since we important more than we export, we are always owing Japan money for the difference in items that we can not evenly trade.
