WorldPlot and crosshatching countries

This shouldn't be difficult but after having spent some time on it, I
haven't made any headway. I am trying to illustrate two variables on a world
map. The first is illustrated using color. The second, a binary variable, by
a thick, black border. Instead of using the thick, black border, I'd like to
use vertical, diagonal, or horizontal cross hatching. Below is some simple
code which illustrates the process using the thick, black border. How do I
use cross hatching? I am using version 6.

Best,

Daniel

<< WorldPlot`
border = {Black, Thickness[.01]};
country1 = {"USA", "China", "Nigeria"};
country2 = {"China"};
color1 = {Blue, Red, Yellow};
color2 = {Hue[3, 1, 1, .01]};
map1 = WorldPlot[{country1, color1}, WorldToGraphics -> True,
  WorldGridBehind -> True, WorldBackground -> White,
  WorldGrid -> None, ImageSize -> {500}]
map2 = WorldPlot[{country2, color2}, WorldToGraphics -> True,
  WorldBorders -> border, WorldGrid -> None, ImageSize -> {500}]
finalmap = Show[{map1, map2}]
